What‘s your expect of the output?:
console.log(0.1 + 0.2 === 0.3);
The answer is ‘false‘.
Because:
0.1+ 0.2 // 0.30000000000000004
Therefore if we do calculation on Frontend:
const price = 9.33; const quantity = 3; console.log(price * quantity); // 27.990000000000002
The result is not correct.
The solution for this:
const anotherPrice = 9.33 * 100; const anotherQuantity = 3; console.log((anotherPrice * anotherQuantity) / 100); // 27.99
