sgc-unit

PREVIEW RELEASE This is a copy of original ethjs-unit, changed as per ether-unit requirements!

sgc-unit

A simple module for handling SGC unit convertion.

Install

npm install --save sgc-unit@latest

Usage

const unit = require('sgc-unit');

var val1 = unit.toWei(249824778, 'sgc');

// result <BN ...> 249824778000000000000000000

var val2 = unit.fromWei('249824778000000000000000000', 'sgc');

// result '249824778'

Amorphic Data Formatting

sgc-unit uses the number-to-bn module to format all number values (hex or otherwise) into digestable BN.js number instances.

Methods Available & Objects

unitMap         { unitName: singleUnitWeiValue, ... }
getValueOfUnit  <Function (unit) : (BN)>
toWei           <Function (value, unit) : (BN)>
fromWei         <Function (value, unit) : (String)>

Why BN.js?

ether has made a policy of using BN.js accross all of our modules. Here are some reasons why:

1. Lighter than alternatives (BigNumber.js)
2. Faster than most alternatives, see benchmarks
3. Used by the Ethereum foundation across all ethereumjs repositories
4. Is already used by a critical JS dependency of many ethereum packages, see package elliptic
5. Does not support decimals or floats (for greater precision), remember, the Ethereum blockchain cannot and will not support float values or decimal numbers
