Direct3D 11 defines the same requirement: 32-bit floating-point operations produce a result that is within 0.5 unit-last-place (ULP) of the infinitely-precise result. The standard defines five rounding rules. The first two rules round to a nearest value; the others are called directed roundings: • Round to nearest, ties to even – rounds to the nearest value; if the number falls midway, it is rounded to the nearest value with an even least significant digit. • Round to nearest, ties away from zero (or ties to away) – rounds to the nearest value; if the number falls midway, it is rounded to t… fatcow pop email settings
