Crate num_integer

Integer trait and functions.

Compatibility

The num-integer crate is tested for rustc 1.8 and greater.

Structs

ExtendedGcd

Greatest common divisor and Bézout coefficients

IterBinomial

An iterator over binomial coefficients.

Traits

Average

Provides methods to compute the average of two integers, without overflows.

Integer

Roots

Provides methods to compute an integer’s square root, cube root, and arbitrary nth root.

Functions

average_ceil

Returns the ceiling value of the average of x and y – see Average::average_ceil.

average_floor

Returns the floor value of the average of x and y – see Average::average_floor.

binomial

Calculate the binomial coefficient.

cbrt

Returns the truncated principal cube root of an integer – see Roots::cbrt.

div_ceil

Ceiled integer division

div_floor

Floored integer division

div_mod_floor

Simultaneous floored integer division and modulus

div_rem

Simultaneous integer division and modulus

gcd

Calculates the Greatest Common Divisor (GCD) of the number and other. The result is always positive.

gcd_lcm

Calculates the Greatest Common Divisor (GCD) and Lowest Common Multiple (LCM) of the number and other.

lcm

Calculates the Lowest Common Multiple (LCM) of the number and other.

mod_floor

Floored integer modulus

multinomial

Calculate the multinomial coefficient.

nth_root

Returns the truncated principal nth root of an integer – see Roots::nth_root.

sqrt

Returns the truncated principal square root of an integer – see Roots::sqrt.
