* chore(package): update standard to version 12.0.0
* update to new lint version with --fix
I believe this mainly adds whitespace to `{}`'s.
* Replace assert.equal with assert.strictEqual
This breaks a lot of tests which I will endevour to fix in the next
commits.
* Fix most errors due to assert.strictEquals
Some instances of `strictEquals` are replaced by `deepEquals`.
`toString` has been used to make some string comparisions explicit.
Tests will still fail untill #1236 and #1237 are fixed.
* Fix assertion erros due to -0
With node 10, assert.strictEqual no longer considers `0 === -0`.
I missed these first time round as I was using node 8.
* Put toString correct side of bracket
I was converting the constructor to a string rather
than the result of the computation. Oops.
* Fixed #1236: quantileSeq has inconsistant return
* Update package-lock
* Fixed #1237: norm sometimes returning a complex number instead of number
* Fix cli tests
* More changes for standardjs, and fixes in unit tests

* Round a value towards minus infinity.

* For matrices, the function is evaluated element wise.

*
|
|
* Syntax:
|
|
*
|
|
* math.floor(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.floor(3.2) // returns number 3
|
|
* math.floor(3.8) // returns number 3
|
|
* math.floor(-4.2) // returns number -5
|
|
* math.floor(-4.7) // returns number -5
|
|
*
|
|
* const c = math.complex(3.2, -2.7)
|
|
* math.floor(c) // returns Complex 3 - 3i
|
|
*
|
|
* math.floor([3.2, 3.8, -4.7]) // returns Array [3, 3, -5]
