pub struct Rational128(_, _);
Expand description

A wrapper for any rational number with a 128 bit numerator and denominator.

Implementations

Zero.

One

If it is zero or not

Build from a raw n/d.

Build from a raw n/d. This could lead to / 0 if not properly handled.

Return the numerator.

Return the denominator.

Convert self to a similar rational number where denominator is the given den. This only returns if the result is accurate. None is returned if the result cannot be accurately calculated.

Get the least common divisor of self and other.

This only returns if the result is accurate. None is returned if the result cannot be accurately calculated.

A saturating add that assumes self and other have the same denominator.

A saturating subtraction that assumes self and other have the same denominator.

Addition. Simply tries to unify the denominators and add the numerators.

Overflow might happen during any of the steps. Error is returned in such cases.

Subtraction. Simply tries to unify the denominators and subtract the numerators.

Overflow might happen during any of the steps. None is returned in such cases.
