/**
* Calculates the modulus, the remainder of an integer division.
*
* For matrices, the function is evaluated element wise.
*
* The modulus is defined as:
*
* x - y * floor(x / y)
*
* See https://en.wikipedia.org/wiki/Modulo_operation.
*
* Syntax:
*
* math.mod(x, y)
*
* Examples:
*
* math.mod(8, 3) // returns 2
* math.mod(11, 2) // returns 1
*
* function isOdd(x) {
* return math.mod(x, 2) != 0
* }
*
* isOdd(2) // returns false
* isOdd(3) // returns true
*
* See also:
*
* divide
*
* @param {number | BigNumber | Fraction | Array | Matrix} x Dividend
* @param {number | BigNumber | Fraction | Array | Matrix} y Divisor
* @return {number | BigNumber | Fraction | Array | Matrix} Returns the remainder of `x` divided by `y`.
