* fix(simplify): Leave string constants as strings.
Note that because the `size` built-in function called on a string returns
a Matrix, which is represented in math.js expressions as an Array, this
commit has to add ArrayNode as a dependency of `simplify` (and hence
also of `rationalize`).
In addition, it requires changing the handling of ArrayNodes
and AccessorNodes in `simplifyConstant` from "unimplemented" to just a
pass-through (since a full implementation of simplification in Arrays and
indexing seemed beyond the scope of this change, but `simplify` must not
throw an error on `size("foo")`). Hence, this commit also adds skipped unit
tests for some expressions with arrays and indexing that should ultimately
simplify.
It also removes the skip on the test group "should not change the value of
numbers when converting to fractions (3)" since all of those tests already
appear to pass.
Resolves#2152.
Changes the behavior in #1913 from throwing an error to allowing Arrays and
indexes but not simplifying inside them.
* chore: Fix lint and remove explanatory comment
* refactor(gamma function): use lanczos approximation with comments
* tests: additional checks for specific numbers
* tests: check for value close to re(0.5)
* refactored intersect, fixed it not returning null for matrix input
* intersect: improved flattening algorithm, added tests

* added support for word size suffix in getToken
* start modifying number(string) to support word size suffix for signed integers
* word size suffixes for Number
* initial support for BigNumber
* fix linter issues
* remove unused variable
* start extending bitwise operators for Number for values greater than 32 bits
* Revert "start extending bitwise operators for Number for values greater than 32 bits"
This reverts commit 6fac1a7b10665a221ab5de521c08fa9fcf959eb1.
* add a test for 53 bit literal
* added an optional second argument to bin, oct, and hex to allow formatting signed numbers with custom word size
* removed size checks
* Attempted to extend bin, oct, hex format functions to work with BigNumber, but not working fully.
Apparently Decimal.js toString method doesn't take a base parameter like js number does. I guess I have to do the formatting myself.
* Added n2base function to do formatting for BigNumber.
* Added check for zero in n2base.
* Removed old failing tests.
* Added some tests (failing).
* Extended 'format' function with 'base' and 'wordSize' options and changed 'bin', 'oct', and 'hex' to use 'format' function.
* Fixed lint issues.
* Fixed issues related to the merge.
* Corrected a test.
* Fixed bignumber formatter.
* Added tests for math.format with 'base' and 'wordSize' options.
* Fixed lint issue.
* Changed 'base' option to 'bin', 'oct', and 'hex' values for 'notation' option of 'format' function.
* Added word size suffix to the output of format, bin, oct, and hex.
* Updated documentation.
* emplementing rotate(w, theta)
* will return same type as input
* edge cases arraySize
* rising coverage
* making result type predictable
