27 sie 2009 · float nearest = roundf(val * 100) / 100; /* Result: 37.78 */. float rounded_up = ceilf(val * 100) / 100; /* Result: 37.78 */. Notice that there are three different rounding rules you might want to choose: round down (ie, truncate after two decimal places), rounded to nearest, and round up.
