round-string

Round numbers with arbitrary precision.

Usage

round('149', 3)

// => 15

round('149', 1)
// => 1

round('99', 1)

Installation

$ npm install round-string

API

round(num, len)

Reasoning

This module operates on strings instead of numbers, because JavaScript numbers don't support arbitrary precision. Strings however can be as long as you want.
