* Calculate the exponent of a value.
* For matrices, the function is evaluated element wise.
*
* Syntax:
*
* math.exp(x)
*
* Examples:
*
* math.exp(2) // returns number 7.3890560989306495
* math.pow(math.e, 2) // returns number 7.3890560989306495
* math.log(math.exp(2)) // returns number 2
*
* math.exp([1, 2, 3])
* // returns Array [
* // 2.718281828459045,
* // 7.3890560989306495,
* // 20.085536923187668
* // ]

*
* expm1, log, pow
*
* @param {number | BigNumber | Complex | Array | Matrix} x A number or matrix to exponentiate
* @return {number | BigNumber | Complex | Array | Matrix} Exponent of `x`
