pub fn div_rem(&self, other: &BigUint) -> (BigUint, BigUint)

pub fn div_floor(&self, other: &BigUint) -> BigUint

pub fn mod_floor(&self, other: &BigUint) -> BigUint

pub fn div_mod_floor(&self, other: &BigUint) -> (BigUint, BigUint)

pub fn div_ceil(&self, other: &BigUint) -> BigUint

pub fn gcd(&self, other: &BigUint) -> BigUint

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

The result is always positive.

pub fn lcm(&self, other: &BigUint) -> BigUint

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

pub fn gcd_lcm(&self, other: &BigUint) -> (BigUint, BigUint)

Calculates the Greatest Common Divisor (GCD) and Lowest Common Multiple (LCM) together.

pub fn divides(&self, other: &BigUint) -> bool

Deprecated, use is_multiple_of instead.

pub fn is_multiple_of(&self, other: &BigUint) -> bool

Returns true if the number is a multiple of other.

pub fn is_even(&self) -> bool

Returns true if the number is divisible by 2.

pub fn is_odd(&self) -> bool

Returns true if the number is not divisible by 2.

pub fn next_multiple_of(&self, other: &BigUint) -> BigUint

Rounds up to nearest multiple of argument.

pub fn prev_multiple_of(&self, other: &BigUint) -> BigUint

Rounds down to nearest multiple of argument.
