Package Exports
- fixed-number
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (fixed-number) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
fixed-number
Format numbers, percentages and currencies with a fixed number of digits. Succinct wrapper of Intl.NumberFormat defaulting to en-US locale. In terms of functionality it sits between Number.prototype.toFixed and the option-rich (and consequently verbose) Intl.NumberFormat.
Example
const decimal = require('fixed-number')(1, 3)
const percent = require('fixed-number')(2, 1, 'percent')
const usd = require('fixed-number')(2, 2, 'usd')
const eur = require('fixed-number')(3, 0, 'eur')
const custom = require('fixed-number')(1, 1, '+')
console.log(decimal(123456.78900001)) // '123,456.789'
console.log(decimal(NaN)) // '-.---'
console.log(percent(0.2)) // '20.0%'
console.log(usd(19.99)) // '$19.99'
console.log(eur(19.99)) // '€020'
console.log(custom(2)) // '2.0+'API
format = require('fixed-number')(..)
Arguments:
minimumIntegerDigits(number, required)exactFractionDigits(number, required)style(string):'decimal'(default),'percent', a ISO 4217 currency code, or a custom suffix.locale(string): defaults to'en-US'(see Node.js docs for requirements)
Returns a function format that when called with a number, returns a formatted string.
