npm version Build Status Dependency Status devDependency Status

A Node.js library for converting between different numeric representations.

Usage

var NumberConverter = require("number-converter").NumberConverter;

var nc = new NumberConverter(NumberConverter.DECIMAL, NumberConverter.ROMAN_NUMERAL);
console.log(nc.convert(1234)); // MCCXXXIV
console.log(nc.deconvert("MCMXCIX")); // 1999

Number Types

A NumberConverter can convert between different numeric representations specified in its constructor. To convert between hexadecimal and binary, write:

var nc = new NumberConverter(NumberConverter.HEXADECIMAL, NumberConverter.BINARY);
console.log(nc.convert("F8F")); // "111110001111"

Here are the available number types:

  • NumberConverter.DECIMAL - Base-10 number system (digits 0-9)
  • NumberConverter.BINARY - Base-2 number system (digits 0 and 1)
  • NumberConverter.OCTAL - Base-8 number system (digits 0-7)
  • NumberConverter.HEXADECIMAL - Base-16 number system (digits 0-9 and letters A-F)
  • NumberConverter.ROMAN_NUMERAL - Numeric system used in ancient Rome (letters I, V, X, L, C, D and M)
  • NumberConverter.SCIENTIFIC_NOTATION - Scientific notation: a way of writing numbers too large or small to be conveniently written as decimal (e.g. 5200000 -> 5.2e6)
