Math.Pow() vs Math.Exp() C# .Net

.net, algebra, c#, calculus, pow

Solution

`Math.Pow` computes x y for some x and y.

`Math.Exp` computes e x for some x, where e is Euler's number.

Note that while `Math.Pow(Math.E, d)` produces the same result as `Math.Exp(d)`, a quick benchmark comparison shows that `Math.Exp` actually executes about twice as fast as `Math.Pow`:

Trial Operations       Pow       Exp
    1       1000 0.0002037 0.0001344 (seconds)
    2     100000 0.0106623 0.0046347 
    3   10000000 1.0892492 0.4677785

Problem

Can anyone provide an explanation of the difference between using `Math.Pow()` and `Math.Exp()` in C# and .net ? Is `Exp()`just taking a number to the Power using itself as the Exponent?
