zero-decimal-currencies

Features

Get the smallest currency unit even it is a Zero Decimal Currency

This lib will convert the amount to the smallest currency unit (e.g., 100 cents to charge €1.00 or 100 to charge ¥100, a zero-decimal currency).

Install

npm install zero-decimal-currencies

Usage

const smallestUnit = require("zero-decimal-currencies");
//or import smallUnit from 'zero-decimal-currencies';

//smallestUnit(amount, currency, display, noRound);

let amount = smallestUnit(100.01, "JPY"); //you don't want to display ¥100.01 to your customer, neither charge 100 times the correct amount
console.log(amount); //'100'

let amount2 = smallestUnit(100.01, "JPY", true); //even display mode set to true, will be nice to zero-decimal currencies
console.log(amount2); //'100'

let amount3 = smallestUnit(100.51, "JPY"); //by default will round up with zero-decimal currencies
console.log(amount3); //'101'

let amount4 = smallestUnit(100.01, "EUR"); //non zero-decimal currency, not useful to display, but useful to charge in Stripe
console.log(amount4); //'10001'

let amount5 = smallestUnit(100.01, "EUR", true); //non zero-decimal currency, useful to display, but not useful to charge in Stripe
console.log(amount5); //'100.01'

let amount6 = smallestUnit(15.7784514, "EUR"); //round is default, using toFixed rules
console.log(amount6); //'1578'

let amount7 = smallestUnit(15.7784514, "EUR", false, true); //the last parameter is a noRound option, that always get the 2 first decimals even a big decimal (that js put in cientific notation)
console.log(amount7); //'1578'
