log function problem

[clarkk]

Hi guys,

i am trying to remove 'delta' from this equation:

R = (double)(c*log(k/delta)*pow((double)k, 0.5));

but when i try:

R = (double)(c*log(k)*pow((double)k, 0.5));

i keep getting error C2668: 'log' : ambiguous call to overloaded function

Any ideas on how to solve this!?

k is an integer and log has no overload for an integer argument. The compiler can't decide whether it should convert it to float or double. Write log(float(k))

Thats great, tnx hamsterman!
