Math.js is an extensive math library for JavaScript and Node.js. It features a flexible expression parser with support for symbolic computation, comes with a large set of built-in functions and constants, and offers an integrated solution to work with dif

   * 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.
   *
   * 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.map([1, 2, 3], math.exp)
   *    // returns Array [
   *    //   2.718281828459045,
   *    //   7.3890560989306495,
