floating point round in C++

[John Smith]

Hello, is there a way to implement the floating point version of round?
usually for int's it's int(num+.5) but how to do it for floats?

Thanks.

#include <math.h>

double d = floor(num+.5);

Yeah ...

int(4.49 + 0.5)

Just let me know which bank you're working for lest I'm opening
an account there.

Cheers,

PS: C99 knows of round(double) and roundf(float).
