V11 with typed-function@3 (#2560)
* refactor: Remove the automatic conversion from number to string. (#2482)

This is a breaking change. However, nothing in the unit tests or examples
  actually depended on such a conversion, and it's difficult to construct
  situations in which it's necessary. The best such example is e.g.
  `count(57)` which formerly gave the number of digits in its numeric
  argument. Of course, after this commit, that behavior can still be
  obtained by the just slightly longer expression `count(string(57))`

  The change is proposed in preparation for an addition of new facilities/
  handlers to allow symbolic computation in a couple of different ways
  (see #2475 and #2470).

* feat(simplifyCore): convert equivalent function calls into operators (#2466)

* feat(simplifyCore): convert equivalent function calls into operators

  Resolves #2415.

* docs: Every operator has a function form

  Also documents the new behavior of simplifyCore to convert function calls
  into any equivalent operator form they may have. Also fixes the syntax
  errors so that simplifyCore will successfully doctest.

* docs: Fix table syntax for operator->function correspondence

* fix(parse): Implement amended "Rule 2"

  As per the discussion in #2370, the amended "Rule 2" is
  "when having a division followed by an implicit multiplication, the
   division gets higher precedence over the implicit multiplication when
   (a) the numerator is a constant with optionally a
       prefix operator (-, +, ~), and
   (b) the denominator is a constant."
  This commit implements that behavior and adds tests for it.
  Resolves #2370.

* fix: OperatorNode.toString() outputs match implicit multiplication parsing

  Also greatly extends the tests on OperatorNode.toString() and .toTex(), and
  ensures that all tests are performed on both. (toHTML() is still a testing
  stepchild.)
  Also fixes other small bugs in .toString() and .toTex() revealed by the
  new tests.
  Resolves #1431.

* test(parse): More cases of implicit multiplication

* refactor: Alter the precedence of implicit multiplication

  This greatly simplifies OperatorNode:calculateNecessaryParentheses,
  as opposed to trying to correct for the change in precedence after
  the fact.

* Fix broken unit test

* Replace `options && options.implicit` with `options?.implicit`

* Replace `options?.implicit` with `options && options.implicit` again, it breaks the Node 12 tests

* chore: Prevent confusion with standard matrix functions. (#2465)

* chore: Prevent consfusion with standard matrix functions.

  Prior to this commit, many functions operated elementwise on matrices
  even though in standard mathematical usage they have a different
  meaning on square matrices. Since the elementwise operation is easily
  recoverable using `math.map`, this commit removes the elementwise
  operation on arrays and matrices from these functions.
  Affected functions include all trigonometric functions, exp, log, gamma,
  square, sqrt, cube, and cbrt.
  Resolves #2440.

* chore(typescript): Revise usages in light of changes

  sqrt() is now correctly typed as `number | Complex` and so must
  be explicitly cast to number when called on a positive and used
  where a Complex is disallowed; sqrt() no longer applies to matrices
  at all.

* feat: Provide better error messages for v10 -> v11 transition

  Uses new `typed.onMismatch` handler so that matrix calls that used to
  work will suggest a replacement.

* Fix #2412: let function diff return an empty matrix when the input contains only one element (#2422)

* Fix #2412: let function diff return an empty matrix when the input has only one element

* Undo changes in History in this fixme

* Add TypeScript definitions for src/utils/is.js (#2432)

This is a first step toward full publication of these functions,
that were already being exported by mathjs but had not yet
had the associated actions (documentation/available in 
parser/typed, etc.) Also, makes most of them into TypeScript
type guards, and adds Matrix as a constructor type. Resolved #2431.

* Refactor/simplify core cleanup (#2490)

* refactor: don't simplify constants in simplifyCore

  Keeps the operation of simplifyCore cleanly separate from
  simplifyConstant.

* fix; handle multiple consecutive operations in simplifyCore()

   Also adds support for logical operators.
   Resolves #2484.

* feat: export simplifyConstant

  Now that simplifyCore does not do any constant folding, clients may
  wish to access that behavior via simplifyConstant. Moreover, exporting it
  makes it easier to use in custom rule lists for simplify().

  Also adds docs, embedded docs, and tests for simplifyConstant().

  Also fixes simplifyCore() on logical functions (they always return boolean,
  rather than "short-circuiting").

  Resolves #2459.

* refactor: Rename matrix algorithms to stay sane in next refactor

* refactor: Create a generator for boilerplate matrix versions of operations

  This reduces code length and duplication, and significantly reduces the
  number of instances of 'this' that will require replacement when moving on
  top of typed-function v3.

* refactor: add automatic conversion from string to Node

  Eliminates many `this` calls in src/function/algebra, which will help
  conversion to typed-function v3a.

  Also make `resolve` into a typed function so that it will now work
  on strings as well, and adds a test that it does.

* refactor: Use temporary conversions to simplify typed-function definitions

  Specifically, temporarily converting Object to Map eases the definition
  of 'simplify' and a new, generally ignored type 'identifier' (a subtype
  of 'string') with a temporary conversion to 'SymbolNode' simplifies the
  definition of 'derivative'.

  These refactors eliminate multiple instances of this, which will ease
  conversion to typed-function v3a.

* refactor: Speed up utils/is.js typeOf function

  In preparation for using it as the function selector for the Unit class.
  Also fixes the inconsistency between the `typed` type hierarchy
  'function' and typeOf returning 'Function' in favor of
  'function', again to minimize the special cases in typeOf

* feat(Unit): Add a method giving the (string name of the) type of the value

  E.g. `math.unit('5cm').valType()` returns `number`.

  Also uses this for an internal method that directly gives the number
  converter for a Unit.

  Also fixes lint errors from previous commit (not clean, I know, I forgot
  that build-and-test does not run lint).

  Adds tests for unit.valType()

* refactor: Eliminate hyperbolic functions operating on angles

  There is no mathematical meaning to a hyperbolic function operating on
  an angle (the proper units of its argument is actually area), and it
  eliminates a number of uses of `this`, so remove such arguments.

* refactor: Remove miscellaneous unnecessary typed-function this refs

* refactor: Adapt to typed-function v3a

  Mostly this involves replaceing instances of 'this' with used of (preferably)
  typed.referTo() or typed.referToSelf(). Some repeated batterns of boilerpolate
  signatures within different divisions of functions (bitwise, relational,
  trigonometry) were factored out into their own files and reused in several
  of the individual functions.

* tests: Only require that derivative tests mention the proper node type

* refactor: remove typed.ignore

* chore: Update to typed-function 3.0

  Also had to deal with new typing for `resolve()` in that it now accepts
  strings and Matrices; added tests for the new possibilities for `resolve()`,
  and eliminated empty comments from the Node representation of parsed
  strings as they can't really be doing anyone any good and they are a pain
  for testing.

  Also updates the TypeScript declarations and tests for `resolve()`

* chore: Object.hasOwn not supported in Node 14

  Also removes 'resolve' from the known failing doc tests, now that it handles
  strings.

* chore: Drop ES5 / IE 11 support.

* fix(types): Remove no-longer-implementd matrix overloads

* test(identifier): As requested in review item 2

* refactor(Unit): valType => valueType as per review item 3

* test(hasNumericValue): Test boolean arguments as per review item 4

* refactor(Node): Use class syntax rather than assigning prototypes

  This change simplifies the typeOf() function, because now all subclasses
  of Node have the expected constructor name.

  Also, reformats the documentation of the typeOf() function so that the
  doc test of that function will serve as an exhaustive test that the bundle
  returns the proper types.

* Prevent chain functions from matching stored value with a rest parameter (#2559)

* chore: Prevent confusion with standard matrix functions. (#2465)

* chore: Prevent consfusion with standard matrix functions.

  Prior to this commit, many functions operated elementwise on matrices
  even though in standard mathematical usage they have a different
  meaning on square matrices. Since the elementwise operation is easily
  recoverable using `math.map`, this commit removes the elementwise
  operation on arrays and matrices from these functions.
  Affected functions include all trigonometric functions, exp, log, gamma,
  square, sqrt, cube, and cbrt.
  Resolves #2440.

* chore(typescript): Revise usages in light of changes

  sqrt() is now correctly typed as `number | Complex` and so must
  be explicitly cast to number when called on a positive and used
  where a Complex is disallowed; sqrt() no longer applies to matrices
  at all.

* feat: Provide better error messages for v10 -> v11 transition

  Uses new `typed.onMismatch` handler so that matrix calls that used to
  work will suggest a replacement.

* fix: prevent chain from matching rest parameter with stored value

  Since the revised code needs the isTypedFunction predicate, switch to using
  the typed-function implementation for that throughout mathjs, rather than
  rolling our own here.

  Also adds a test that chain() no longer allows this kind of usage.

  Removes the two type declarations in types/index.d.ts that were allowing
  this sort of "split rest" call and added tests that such calls are
  forbidden.

  Adds to the chaining documentation page that such "split" calls are not
  allowed.

* chore: Refresh this PR to reflect underlying changes

  Also addresses the review request with a detailed comment on the
  correctness of a new code section.

  Note that it reverts some changes to the TypeScript signatures of the
  matrix functions ones() and zeros() -- they do not actually have a
  typed-function signature of two numbers and an optional format
  specifically for two dimensions. What they have is a single rest
  parameter, from which the format is extracted if present.

  Hence, due to the ban on breaking rest parameters, it is not
  valid to call math.chain(3).zeros(2) to make a 3-by-2 matrix of zeros,
  which seems like a perfectly valid ban as the division of the dimensions
  is very confusing; this should be written as math.chain([3,2]).zeros().
  The TypeScript signatures are fixed accordingly, along with the edge
  case of no arguments to ones() and zeros() at all, which does work to
  produce the "empty matrix".

fix(combinations): Extend range of exact values (#2414)
Prior to this change, combinations(42,21) did not return an integer,
  despite its value being well below MAX_SAFE_INTEGER. Now the
  multiplications and divisions are balanced to try to keep the
  intermediate results within the safe range.

  Adds a couple of tests for larger values of combinations().

  Resolves #2413.
