This issue is created to track the discussion in the comment --> #97529 (comment)
PR #97529 changes the behavior of floating point to integer conversions on x86/x64. It allows the conversions to follow saturating behavior which .NET wants to standardize on.

    Just noting that this applies to all floating point -> integer conversions, they should all saturate under the new behavior we're standardizing against.
