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 { default: Decimal } = require('decimal.js');

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

// Decimal
console.log(new Decimal(amountAvailable).times(exchangeRate).toNumber()); // 1197.5376
console.log(new Decimal(quantityArs).div(exchangeRate).toNumber()); // 1.12
console.log(new Decimal(quantityArs).div(exchangeRate).toDecimalPlaces(2, Decimal.ROUND_UP).toNumber()); // 1.13
console.log(new Decimal(1.12).toDecimalPlaces(2, Decimal.ROUND_UP).toNumber()); // 1.12

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

That's exactly what I did, when I convert it to number with toNumber it returns 1.12, but when I round it up to two decimals ir wrongly returns 1.13

No, the rounding is not incorrect.

Please post the exact value you are trying to round, i.e post the toString value of new Decimal(quantityArs).div(exchangeRate), then it should be obvious the rounding is correct.
