rounding

[peterworth]

whats the easiest way to round a float down? (so that a double like 2.8 becomes an int value of 2)

 

[Zyrenthian]

float f = 2.8;
int x = (int)f;

will a cast always round down? i thought that would make x = 3

Remember double floor(double) - ANSI/ISO Standard Library function from <cmath> (former <math.h>). It's exactly round down for positive numbers...
