Constants§

PCG_MUL_64: This is the suggested multiplier for a PCG with 64 bits of state.

ieee754_random_f32: Generates an f32 in the signed or unsigned unit range.
ieee754_random_f64: Generates an f64 in the signed or unsigned unit range.
lcg32_jump: Advance a 32-bit LCG by delta steps in log2(delta) time.
lcg32_step: Advance a 32-bit LCG’s state.
lcg64_jump: Advance a 32-bit LCG by delta steps in log2(delta) time.
lcg64_step: Advance a 32-bit LCG’s state.
lcg128_jump: Advance a 32-bit LCG by delta steps in log2(delta) time.
lcg128_step: Advance a 32-bit LCG’s state.
next_binary_exp_distr32: Returns k with probability 2^(-k-1), a “binary exponential distribution”.
xsh_rr_u64_to_u32: “Xor-shift high bits” then “randomized rotate”, u64 down to u32.
xsl_rr_u128_to_u64: “Xor-shift low bits” then “randomized rotate”, u128 to u64.
