Need to Calculate NON-Integer Exponents...

[onrdbandit]

Hello,

In my current project, I need to calculate decimal exponents. The ultimate goal is calculating Nth roots of numbers. The only methods I can find (Newton's Method and a thing working w/ Logs) both require the use of decimal exponents. These methods dont help any. To handle them, I have to calculate a decimal exponent, and if I could do this, I could simply calculate the root myself. But I dont know a function that allows for the raising of any number (preferably a double or a long double) to a non-integer power.

Does anyone know of a process or a function that can do this? I REALLY NEED THIS!

Thanks,

try with:
pow (exponent);

exponent could be a float number

and you must include the math.h library

Thanks a bunch!

It works great. Somehow I managed to miss that function in the help files. The reason I tried the above methods, was because I found pow10 and pow10l. They would have been needed in the case of the above methods, but they truncate their arguments to integers, and lose the decimal value.

Thanks again,
