Base Converter (dpm-base)

A simple JavaScript library for converting numeric bases. Comprised of modules binary, octal, decimal and hex - supporting functions for conversion of base-2, base-8, base-10 and base-16. Conversion logic written in JavaScript, with support for big number calculations via bignumber.js dependancy.

Limitations

• Currently only support conversion of whole number values - no fractional values as of yet. Support for fractional conversion may be added in the future.

Installation

npm install dpm-base

API Documentation

Usage

importing package in script

const base = require('dpm-base');

Conversions

Each module contains four basic conversion functions:

• toBin(value) - for conversion from base to binary (base-2)
• toOct(value) - for conversion from base to octal (base-8)
• toDec(value)- for conversion from base to decimal (base-10)
• toHex(value) - for conversion from base to hexadecimal (base-16)

Converted values return as String

These conversion functions return null if supplied value is invalid

Each module also supports converting from its base to the same base, which means it simply returns the same value supplied.

Additionally, each module has a function for validating number is valid base value

• isValid(value)

Binary

Binary is valid

let isValid = base.binary.isValid(1001);

Binary to Binary

let result = base.binary.toBin(1001);

Binary to Octal

let result = base.binary.toOct(1001);

Binary to Decimal

let result = base.binary.toDec(1001);

Binary to Hexadecimal

let result = base.binary.toHex(1001);

Octal

Octal is valid

let isValid = base.octal.isValid(1001);

Octal to Binary

let result = base.octal.toBin(1001);

Octal to Octal

let result = base.octal.toOct(1001);

Octal to Decimal

let result = base.octal.toDec(1001);

Octal to Hexadecimal

let result = base.octal.toHex(1001);

Decimal

Decimal is valid

let isValid = base.decimal.isValid(1001);

Decimal to Binary

let result = base.decimal.toBin(1001);

Decimal to Octal

let result = base.decimal.toOct(1001);

Decimal to Decimal

let result = base.decimal.toDec(1001);

Decimal to Hexadecimal

let result = base.decimal.toHex(1001);

Hexadecimal

Hexadecimal is valid

let isValid = base.hex.isValid(1001);

Hexadecimal to Binary

let result = base.hex.toBin(1001);

Hexadecimal to Octal

let result = base.hex.toOct(1001);

Hexadecimal to Decimal

let result = base.hex.toDec(1001);

Hexadecimal to Hexadecimal

let result = base.hex.toHex(1001);

Hexadecimal alphanumeric digit to numeric

let result = HEX_ALPHA_TO_DIGIT['a']; // result = '10'

Hexadecimal numeric to alphanumeric digit

let result = HEX_ALPHA_TO_DIGIT['15']; // result = 'f'
