Module randomize::formulas

Base formulas used elsewhere in the crate.

Constants

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

Functions

• 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.
