If the variable p is an integer, however, by C's integer division rules 1/p will be 0 whenever p != 1. pow(x, 1.0/p) will probably do what you want.


Thanks Charlton

Next question regards floor(). if pow(x, 1.0/3) returns a value that can be represented as an integer (like 6.000000) executing floor (6.000000) returns 5.000000. Why isn't it returning 6? I looked at the various round functions but it doesn't look like you can tell them to round down.
