finding e to the power of a value

[calco88]

I am in a hole here, I guess this is more of a basic math question more than anything, but I have a program that at one point needs to find the value of e to the power of another value. How can I get e^someValue? I'm not sure if it involves using log?

Yes I know that I can use pow(e,someValue) what I am asking is, is there any way to do that without declaring e?

Not that I know of, no.

e has a value (from wikipedia e = 2.71828182845904523536, to 20 decimal places)
just make "e" a global constant
