Floats

Package floats provides the implementation of a few additional operations (square root, exponentiation, natural logarithm, exponential function) for the standard library big.Float type.

Install

go get github.com/ALTree/floats

Please note that floats requires Go >= 1.5 (since the big.Float type is not available in previous versions).

Example

package main

import (
	"fmt"
	"math/big"

	"github.com/ALTree/floats"
)

func main() {
	const prec = 200 // 200 binary digits
	two := new(big.Float).SetPrec(prec).SetInt64(2)

	z := floats.Sqrt(two) // z.Prec is automatically set to 200

	fmt.Printf("sqrt(2) = %.50f...\n", z) // print the first 50 decimal digits
}

outputs

sqrt(2) = 1.41421356237309504880168872420969807856967187537694...
