numberFormat(inputNumber, precision, digit, separator, decimalChar)

Parameters:

• inputNumber（required） : {(Number|String)} Number to format .
• optionalPrecision: {Number} precision for the decimal .

bindWith(precision, digit, separator, decimalChar)

The numberFormat function accepts these same parameters as the second and third params. This prevents using currying to bind them and reuse that bound function.

The bindWith function accepts the options and returns a function bound with them.

var numberFormat = require('number-formatierer')
//import numberFormat from 'number-formatierer' ES6

const _bindWith = numberFormat.bindWith(2, 4, ",", ".")
_bindWith(131277.092213);  // 13,1277.09

toFixed(num, precision)

same as number.toFixed and More accurate than number.toFixed

Parameters:

• num（required） : {(Number)} Number .
• precision: {Number} precision for the decimal . default 3 .

var numberFormat = require('number-formatierer')
//import numberFormat from 'number-formatierer' ES6

numberFormat.toFixed(0.015, 2); // 0.02
numberFormat.toFixed(0.025, 2);  // 0.03
numberFormat.toFixed(0.035, 2);  // 0.04
numberFormat.toFixed(0.045, 2);  // 0.05

(0.015).toFixed(2); //0.01
