/**
|
|
* Calculate the absolute value of a number. For matrices, the function is
|
|
* evaluated element wise.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.abs(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.abs(3.5) // returns number 3.5
|
|
* math.abs(-4.2) // returns number 4.2
|
|
*
|
|
* math.abs([3, -5, -1, 0, 2]) // returns Array [3, 5, 1, 0, 2]

* A number or matrix for which to get the absolute value
|
|
* @return {number | BigNumber | Fraction | Complex | Array | Matrix | Unit}
|
|
* Absolute value of `x`
