Set Decimal Places

This helper allows to format a number to show a selected number of decimal places.

import { setDecimalPlaces } from 'mz-math';

const res = setDecimalPlaces(1.2345, 2); // 1.23
const res = setDecimalPlaces(1.2399, 2); // 1.24
const res = setDecimalPlaces(1.2399, 0); // 1

The result of this function is a number (not a string), so sometimes fewer decimal places will be displayed after rounding:

const res = setDecimalPlaces(1.239999, 4); // 1.2400 = 1.24
