Log base 2 using bit operations
Witryna4 sty 2014 · 3/ divides it by three (truncating down), & computes the bitwise AND of the divided value with the original, which will be zero if and only if the input is zero or a power of two (i.e. has at most one bit set), and ! logically negates this, mapping zero to one and all other values to zero. Notes: Witryna11 paź 2024 · Bits are the smallest unit of data used by computers to write instructions. The binary number system runs on bits, which are base-2 numbers representing a logical state of either 0 or 1. Instructions at the processor level are written in machine language using bits.
