Getting started

Fractions is a Go library that adds fraction-like capabilities to Go. If you want to install Fractions simply run the command shown below in your terminal.

go get github.com/TimoKats/fractions

Next, after installing Fractions you can import (and test) the installation with the code shown below. If this outputs 1 2/3 then the installation has been completed correctly.

package main

import (
	"github.com/TimoKats/fractions"
)

func main() {
	y1 := fractions.FloatToFrac(1.67)
	fractions.PrintFrac(y1)
}

Functionalities

This library saves fractions as objects/structs (called frac) and has functions for: printing, setting, getting, formatting and computing. Hereby a short overview of them all.

print functions

• PrintFrac(frac *frac)
• PrintNumerator(frac *frac)
• PrintDenominator(frac *frac)
• PrintInteger(frac *frac)

set functions

• MakeFrac(integer int, numerator int, denominator int)
• SetNumerator(frac *frac, value int)
• SetDenominator(frac *frac, value int)
• SetInteger(frac *frac, value int)

get functions

• GetNumerator(frac *frac)
• GetDenominator(frac *frac)
• GetInteger(frac *frac)

conversion functions

• FloatToFrac(value float64)
• FracToFloat(frac *frac)

formatting functions

• FormatFracOnly(frac *frac)
• FormatSimplify(frac *frac)

operations

• SumFrac(frac1 *frac, frac2 *frac)
• SumInt(frac1 *frac, frac2 *frac)
• SubtractFrac(frac1 *frac, frac2 *frac)
• SubtractInt(frac1 *frac, frac2 *frac)
• SubtractInt(frac1 *frac, value int)
• DivideFrac(frac1 *frac, frac2 *frac)
• DivideInt(frac1 *frac, value int)
• PowerFrac(frac1 *frac, value int)
