@macil/simple-base-converter

This is a fork of https://github.com/sin9270/simple-base-converter changed to publish ES5-compatible code to npm.

Simple math module for base conversion.

Install

npm i @macil/simple-base-converter

Usage

Some bases(2, 8, 16, 32, 36, 62) are predefined.

• _10To2(num)
• _10To8(num)
• _10To16(num)
• _10To32(num)
• _10To36(num)
• _10To62(num)
• _2To10(num)
• _8To10(num)
• _16To10(num)
• _32To10(num)
• _36To10(num)
• _62To10(num)

import { _10To2, _2To10 } from "simple-base-converter";

_10To2(100); // "1100100"
_2To10(1100100); // "100"

// Input can be both integer or string number.
_10To2("100"); // "1100100"
_2To10("1100100"); // "100"

Of course you can choose bases freely.
convertBase(num, originalBase, newBase) converts num from originalBase to newBase.
If you set integer to originalBase or newBase, they are automatically converted by using default base 0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ.

import { convertBase } from "simple-base-converter";

convertBase("20a4", 17, 52); // "3Ag"
convertBase("20a4", "0123456789abcdefg", "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOP"); // "3Ag"

Custom bases are also available.

convertBase(10000, 10, "－・"); // "・－－・・・－－－・－－－－"
convertBase("4649", "0123456789", "零一二三四五六七八九"); // "四六四九"
