greenkeeper[bot] c5971b371a Update standard to the latest version 🚀 (#1226)
* 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 zero.
* For matrices, the function is evaluated element wise.

* Syntax:
*
* math.fix(x)
*
* Examples:
*
* math.fix(3.2) // returns number 3
* math.fix(3.8) // returns number 3
* math.fix(-4.2) // returns number -4
* math.fix(-4.7) // returns number -4
*
* const c = math.complex(3.2, -2.7)
* math.fix(c) // returns Complex 3 - 2i
*
* math.fix([3.2, 3.8, -4.7]) // returns Array [3, 3, -4]
*
* See also:
*
* ceil, floor, round
*
* @param {number | BigNumber | Fraction | Complex | Array | Matrix} x Number to be rounded
* @return {number | BigNumber | Fraction | Complex | Array | Matrix} Rounded value
