The resulting type after applying the / operator.

fn div(self, x: Number) -> Self

Performs the / operation.

fn from(value: u128) -> Self

Converts to this type from the input type.

impl From<u64> for Number

fn from(value: u64) -> Self

Converts to this type from the input type.

impl Mul for Number

type Output = Number

The resulting type after applying the * operator.

Performs the * operation.

impl Ord for Number

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.
