Module statrs::function::factorial

source ·
Expand description

Provides functions related to factorial calculations (e.g. binomial coefficient, factorial, multinomial)

Constants

  • The maximum factorial representable by a 64-bit floating point without overflowing

Functions

  • Computes the binomial coefficient n choose k where k and n are non-negative values.
  • Computes the multinomial coefficient: n choose n1, n2, n3, ...
  • Computes the factorial function x -> x! for 170 >= x >= 0. All factorials larger than 170! will overflow an f64.
  • Computes the natural logarithm of the binomial coefficient ln(n choose k) where k and n are non-negative values
  • Computes the logarithmic factorial function x -> ln(x!) for x >= 0.
  • Computes the multinomial coefficient: n choose n1, n2, n3, ...
