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)
.
