WebDec 24, 2024 · called a pseudorandom-number generator (PRNG). An RNG generates uniformly distributed numbers in the interval (0, 1). A pseudorandom-number generator in SAS is initialized by an integer, called the seed value, which sets the initial state of the PRNG. Each iteration of the algorithm produces a pseudorandom number and advances … Web7. I write a algorithm (taken from "The C Programming Language") that counts the number of 1-bits very fast: int countBit1Fast (int n) { int c = 0; for (; n; ++c) n &= n - 1; return c; } But a friend told me that __builtin__popcount (int) is a lot faster, but less portable. I give it a try and was MANY times faster!
