arithmetic

This package provides basic arithmetic functions without the need for type casting when working with go.

Install

go get https://github.com/NdoleStudio/arithmetic

Or

import "github.com/NdoleStudio/arithmetic"

Benchmarks

This is a benchmark for computing the same functions using this library and doing it natively using type casting. I'm running this tests on a late 2018 a Macbook Pro with 16 GB RAM and a 2.3 GHz Quad-Core Intel Core i5 processor.
