Andi Gallo	e9ad8d5e4f	LibWeb: Use i64 for intermediate value in CSSPixels multiplication ... Reduce the chance of overflow due to fixed point denominator being squared when multiplying the raw values, before adjusting the final value back.	2023-08-04 13:36:29 +02:00
Aliaksandr Kalenik	c431167736	LibWeb: Implement subtraction using saturated_addition in CSSPixels ... Fixes overflow bug found by UBSAN.	2023-07-25 15:21:40 +02:00
Aliaksandr Kalenik	bec07d4af7	LibWeb: Use fixed-point saturated arithmetics for CSSPixels ... Using fixed-point saturated arithmetics for CSSPixels allows to avoid accumulating floating-point errors. This implementation is not complete yet: currently saturated arithmetics implemented only for addition. But it is enough to not regress any of layout tests we have :) See https://github.com/SerenityOS/serenity/issues/18566	2023-07-25 11:52:02 +02:00
