What language are you using? Try 1.0 instead of just 1 to force the result of the division to be a floating point number. For instance, in C#

Code:

int x = 8;  // find the cube root of x, which should be 2

// This returns the wrong result because it uses integer division
Math.Pow(x, 1/3);

// This returns the correct result because it uses floating point division
Math.Pow(x, 1.0/3);
