     20    * Calculate the exponent of a value.
     21    * For matrices, the function is evaluated element wise.
     22    *
     23    * Syntax:
     24    *
     25    *    math.exp(x)
     26    *
     27    * Examples:
     28    *
     29    *    math.exp(2)                  // returns number 7.3890560989306495
     30    *    math.pow(math.e, 2)          // returns number 7.3890560989306495
     31    *    math.log(math.exp(2))        // returns number 2
     32    *
     33    *    math.exp([1, 2, 3])
     34    *    // returns Array [
     35    *    //   2.718281828459045,
     36    *    //   7.3890560989306495,
