Changelog

from	to	description
2.0.1	2.0.5	Added Arithmetic method to UnitValue
	2.0.1	Rewrited the byteConverter implementation in typescript and heavily simplified the algorithm
1.7.10	1.7.11	autoScale now choose between 1000 and 1024 if is decimal type or binary type, the autoscaling is now better

Example

ES6 syntax:

import {
  ByteConverter,
  Unit,
  UnitValue,
  B as Byte,
} from "@wtfcode/byte-converter";

console.log(ByteConverter.convert(Byte.value(1), "b")); //will output 8

console.log(ByteConverter.convert(ByteConverter.value(1024, "MiB"), "GiB")); //will output 1

console.log(new UnitValue(1024, "B").autoScale());

//will output: UnitValue {value: 1, unit: Unit { unit: "KiB", type: "binary", unitOrder: 1, name: "kibibyte" ... } } // the function return a UnitValue scaled

ES5 syntax:

const ByteConverter = require("@wtfcode/byte-converter").default;

console.log(ByteConverter.convert(ByteConverter.value(1024, "MiB"), "GiB")); //will output 1

console.log(ByteConverter.autoScale(ByteConverter.value(0.7, "GB"))); //the function accept a third paramater: an option object

//will output: UnitValue {value: 700, unit: Unit { unit: "MB", type: "decimal", unitOrder: 2, name: "megabyte" ... } }
