- Astonishing IEEE 754: try this in JS, PHP, C# or your preferred programming language:
0.57 - 0.56 → 0.009999999999999898
0.57 - 0.56 == 0.01 → false
0.57 - 0.56 - 0.01 → -1.0234868508263162e-16
0.01 * (-1) * 0 → -0
Surprised? That's why 90% of the applications and probably 99.99%
of the web applications do not need and should never use floating point
numbers; it they do, it is a bug.
