number-convert

A function for converting numbers to and from different bases w/o loss of precision.

Adapted from http://www.danvk.org/hex2dec.html

The problem is that parseInt("0x12345...") isn't precise enough to convert big integers correctly. This uses strings as input and, internally, arrays as workhorses.

API

This module exports a function, convertBase (this function is the module export), with a few shorthand methods (as properties of the exported function).

convertBase(string input, number fromBase, number toBase) : string

Converts a string representation of a number in base fromBase and converts it into a string respresentation in base toBase. That's it.

hexToDec(string input)

Shorthand for convertBase(input, 16, 10).

decToHex(string input)

Shorthand for convertBase(input, 10, 16).

decToBin(string input)

Shorthand for convertBase(input, 10, 2).

binToDec(string input)

Shorthand for convertBase(input, 2, 10).

hexToBin(string input)

Shorthand for convertBase(input, 16, 2).

binToHex(string input)

Shorthand for convertBase(input, 2, 16).
