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" ... } }
