math-conv

Adds new method - Math.conv(), converting numbers between different numeral systems.

Math.conv(sourceSystem, targetSystem, value)

Installation

npm i -P math-conv

Examples

Math.conv(Math.DEC, Math.BIN, 4)
// '100'

Math.conv(Math.BIN, Math.DEC, 100)
// '4'

Specialized Methods

The Math.conv contains a getter that provides an interface to utilize specialized methods:

• binToDec()
• decToBin()
• hexToDec()
• decToHex()
• binToHex()
• hexToBin()

Math.conv.decToBin(4)
// '100'

Math.conv.binToDec(100)
// '4'

Custom Systems

To add a new system use Math.conv.addSystem() method:

Math.conv.addSystem(code, base, addMathConstant = false)

First line in the code below will cause new methods will be accessible:

• value-taking: octToBin(), octToDec() and octToHex()
• value-giving: binToOct(), decToOct() and hexToOct()

Math.conv.addSystem('oct', 8);

const DEC = 24;

Math.conv.decToHex(DEC)
// '18'

Math.conv.hexToOct(18)
// '30'

Math.conv.decToOct(DEC)
// '30'

Built-ins

• Math.BIN for base 2
• Math.DEC for base 10
• Math.HEX for base 16

When adding a new system with the addSystem() method, pass third parameter true to extend Math with a specific constant (uppercase):

Math.conv.addSystem('oct', 8, true);

Math.OCT
// 8
