Pretty currency

Pretty your number or string to a readable currency: 123456789 → '123,456,789'.

Install

npm install --save pretty-currency

Usage

const prettyCurrency = require('pretty-currency')

let num = 123456789
num = prettyCurrency(num)
console.log(num)  // '123,456,789'

num = 123456.7899
num = prettyCurrency(num)
console.log(num)  // '123,456.7899'

the parameter must be a number or string, if not, it will throw a TypeError, for example:

prettyCurrency({})     // Thrown: TypeError: parameter must be a number or string.
prettyCurrency(false)  // Thrown: TypeError: parameter must be a number or string.

if the parameter is string, it must start with number, for example:

prettyCurrency('1234.123forssa')  // '1,234.123'

if not, it will throw an Error, for example:

prettyCurrency('ow1234.123qw')  // Thrown: Error: parameter is invalid.
