A way to safely give programmatically-generated decimal values a little flare! π
This package will coerce the digits of an input value to the nearest user-friendly decimal value, whilst taking care not to exceed caller-defined bounds.
You can download coolnumber from npm:
yarn add coolnumber
It's super easy to use coolnumber
, maybe even too easy, so please take care to specify the max
and min
values if used in a financial applications to prevent your users from getting rekt. If your value cannot be coerced to a coolnumber, it will be returned equal to the original input value but formatted to the requested precision
, which defaults in wei
.
import {coolnumber} from 'coolnumber';
coolnumber({
min: '1',
max: undefined,
value: '1',
coolNumbers: ['69', '420'],
precision: 2,
}); // 1.69 π
coolnumber({
value: '15',
min: '1',
coolNumbers: ['1559'],
precision: 2,
}); // 15.59 π₯
