Web18 feb 2024 · Therefore, we use the dichotomy method to judge whether the high 16 bits have 1. If so, we don't care about the remaining 16 bits (so we need to move 16 bits to the right), and make b16 = 16. If not, we need to look down on whether the 16 bits have 1.

Argument is passed as unsigned int, but it is to be interpreted as the bit-level representation of a single-precision floating point value. Anything out of range (including NaN and infinity) should return 0x80000000u.
