📚 go-fraction

Go Reference

go-fractions is a Go library for working with fractions. It provides a Fraction type for representing fractions, as well as a set of functions for performing operations on fractions such as addition, subtraction, multiplication, and division.

🔨 Usage

To use go-fractions, import the package in your Go code:

import "github.com/nethruster/go-fraction"

You can create a new fraction using the New function

f1, err := fraction.New(1,2) // 1/2, nil
f2, err := fraction.New(2,3) // 2/3, nil
_, err := fraction.New(1,0)  // ErrZeroDenominator

You can perform operations on fractions using the provided functions:

f3 := f1.Add(f2)         // 7/6
f4 := f1.Subtract(f2)    // -1/6
f5 := f1.Multiply(f2)    // 1/3
f6, err := f1.Divide(f2) // 3/4, nil

You can also convert a fraction to a float, or vice versa, using Float64 and FromFloat64 functions:

floatValue := f1.Float64() // 0.5
f7, err := fraction.FromFloat64(0.5) // 1/2, nil

🤔 Rationale

The Fraction type in go-fractions aims to provide a lightweight, primitive-like representation of fractions. As a result, it has limitations in terms of precision and can overflow when performing certain operations. If you need a type that can represent all rational numbers without regard for memory and CPU consumption, consider using the big.Rat type from the standard library.

Please note that these limitations should not be an issue for most use cases, and go-fractions provides a convenient and efficient way to work with fractions in Go. However, it is important to be aware of these limitations and choose the appropriate type based on your specific needs.
