Struct SignedRational

Represents a number that can be expressed as a fraction.

Implements

IEquatable<SignedRational>

Inherited Members

Object.Equals(Object, Object)

Object.GetType()

Object.ReferenceEquals(Object, Object)

Namespace: SixLabors.ImageSharp

Assembly: SixLabors.ImageSharp.dll

Syntax

public readonly struct SignedRational : IEquatable<SignedRational>

Remarks

This is a very simplified implementation of a rational number designed for use with metadata only.
