     12    * Calculate the exponent of a value.
     13    * For matrices, the function is evaluated element wise.
     14    *
     15    * Syntax:
     16    *
     17    *    math.exp(x)
     18    *
     19    * Examples:
     20    *
     21    *    math.exp(2)                  // returns number 7.3890560989306495
     22    *    math.pow(math.e, 2)          // returns number 7.3890560989306495
     23    *    math.log(math.exp(2))        // returns number 2
     24    *
     25    *    math.exp([1, 2, 3])
     26    *    // returns Array [
     27    *    //   2.718281828459045,
     28    *    //   7.3890560989306495,
