rounding a float or double

Or I believe the "ceil" function found in math.h will round numbers as well.

ceil() rounds numbers up, ex ceil(1.1) = 2.0

floor() rounds numbers down, ex floor(1.9) = 1.0

You could make a rounding function like so:

double Round(double d)
{
if (fabs(d - floor(d)) < .5) //Gets the value of decimal part
return floor(d);
else
return ceil(d);
}

*EDIT made that Round function, abs() is for ints.... fabs() is for floats/doubles

I think that double rint (double x) does what you want.
