   * Calculate the exponent of a value.

   * 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,
