Round up returns wrong number

[takihama]

I'm expecting the result of the roundUp to be 1.12, but it returns wrongly 1.13.

const Big = require('big.js');

const amountAvailable = 1.12;
const quantityArs = 1197.5384615384617;
const exchangeRate = 1069.2307692307693;

// Big
console.log(Big(amountAvailable).times(exchangeRate).toNumber()); // 1197.5376
console.log(Big(quantityArs).div(exchangeRate).toNumber()); // 1.12
console.log(Big(quantityArs).div(exchangeRate).round(2, Big.roundUp).toNumber()); // 1.13
console.log(Big(1.12).round(2, Big.roundUp).toNumber()); // 1.12

Look first at the value of Big(quantityArs).div(exchangeRate) and then consider again whether the rounding is incorrect.
