Web2 days ago · Return the mantissa and exponent of x as the pair (m, e). m is a float and e is an integer such that x == m * 2**e exactly. If x is zero, returns (0.0, 0), otherwise 0.5 <= … WebJan 23, 2012 · The estimate is exact when the float is a power of two, and at its worst is about 0.086 too small. In the last of this week’s stupid float tricks I present you with this dodgy code: int RoundedUpLogTwo (uint64_t input) { assert(input > 0); union Float_t num; num.f = (float)input; num.i += 0x7FFFFF; return num.parts.exponent - 127; }
