Bitscan forward
If a set bit is found, the bit position of the first set bit is written to the address specified in the first parameter and the function returns 1. If no bit is found, the function returns 0 and the value written to the address in the first parameter is undefined. See more Search the mask data from least significant bit (LSB) to the most significant bit (MSB) for a set bit (1). See more 0 if the mask is zero; nonzero otherwise.

WebOverloads. LeadingZeroCount (UInt32) Counts the number of leading zero bits in an unsigned 32-bit integer mask. LeadingZeroCount (UInt64) Counts the number of leading zero bits in an unsigned 64-bit integer mask. LeadingZeroCount (UIntPtr) Counts the number of leading zero bits in a mask. Similar in behavior to the x86 instruction LZCNT. WebJan 18, 2008 · scan1 (x, n=0): returns the bit-index of the first 1-bit of x (that is at least n); n must be an ordinary Python int, >=0. If no more 1-bits are in x at or above bit-index n (which can only happen for x>=0, notionally extended with infinite 0-bits), None is returned. x must be an mpz, or else gets coerced to one. setbit (...)
