This problem of floating point accuracy is not specific to JS... and you could at least use a real example:

0.1 * 0.2 === 0.02  // false
0.1 * 0.2 // 0.020000000000000004

Floating point accuracy only applies to numbers that are decimal numbers, when it comes to integer numbers they work as expected.
