Module statrs::function::factorial

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

Constants

MAX_FACTORIAL

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

Functions

binomial

Computes the binomial coefficient n choose k where k and n are non-negative values.

checked_multinomial

Computes the multinomial coefficient: n choose n1, n2, n3, ...

factorial

Computes the factorial function x -> x! for 170 >= x >= 0. All factorials larger than 170! will overflow an f64.

ln_binomial

Computes the natural logarithm of the binomial coefficient ln(n choose k) where k and n are non-negative values

ln_factorial

Computes the logarithmic factorial function x -> ln(x!) for x >= 0.

multinomial

Computes the multinomial coefficient: n choose n1, n2, n3, ...
