help: compiler complains about overloading

[gabriyel]

hi,

i'm using msvs .net 2003. i'm using plain c++. when i compile a piece of code that uses pow(), there are a ton of complains from the compiler than pow() can be overloaded in more than 1 way and it doesn't which way i'm using.

can someone tell me how i can work-around this kind of stringent checks from the compiler?

thanks in advance!

This is very compiler specific, and has nothing to do with strict C/C++ so it has been moved to a more apropriate forum.

If he rephrases the problem then it might be my concern
Post the code gabriyel. If it is standard C++ specific then I'll move it back again. Might as well solve it for you too .

I just ran into this same problem. There are several pow() functions, because they covered all possibilities of argument flavors. I got an error because I happened to use one that didn't exist, pow(int, double). To fix it, I just typecast my int to a double;

int i;
double d, e;
...
e = pow((double)i, d);
