Add API for restoring PseudoRandom and PcgRandom state (#14123) 2024-01-16 23:20:52 +01:00
sfan5 e824e9023f Simplify LuaPseudoRandom::l_next and fix docs
Also extends the allowed range on the C++ side. This has no side-effects.

Fix many issues reported by clang-tidy (#7189)
* Fix many issues reported by clang-tidy

We have many issues in code related to some performance to float <-> double.
Clang-tidy reported it in performance-type-promotion-in-math-fn

I fixed many of them. It's not ready for a promote to blocking

Also fix some value which should be const-ref

est31 738fbc66d0 Fix Lua PcgRandom
Before, this lua code led to a crash:

local pcg = PcgRandom(42)
local value = pcg:next()

This was because if you called s32 PcgRandom::range(min, max) with the
minimum and maximum possible values for s32 integers (which the lua
binding code did), u32 PcgRandom::range(bound) got called with 0 as the
bound. The bound however is one above the maximum value, so 0 is a "special"
value to pass to this function. This commit fixes the lua crash by
assigning the RNG's full range to the bound 0, which is also fits to the
"maximum is bound - 1" principle, as (u32)-1 is the maximum value in the
u32 range.
