<h1 id="function-exp">Function exp <a href="#function-exp" title="Permalink">#</a></h1>

Calculate the exponential of a value.
For matrices, if you want the matrix exponential of square matrix, use
the `expm` function; if you want to take the exponential of each element,
see the examples.

```js

math.pow(math.e, 2)          // returns number 7.3890560989306495
math.log(math.exp(2))        // returns number 2

math.map([1, 2, 3], math.exp)
// returns Array [
