Webrounding can be faster than the default conversion in C. The direct implementation is to treat positive and negative numbers as different cases: float f;/* assume -32768 <= f <= 32767 */ int i; /* could also be “shortint” */ if(f > 0) { i = (int)(f + 0.5); } else { i = (int)(f - 0.5); } WebThese functions are redundant when GNU CC is used, because in GNU C the ‘ / ’ operator always rounds towards zero.
