* Calculate the absolute value of a number. For matrices, the function is

* 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]

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