Purpose

A small test fix based on the net10 change of long.MinValue and long.MaxValue.

• in net9.0 double -> long casts were changed to saturate instead of returning long.MinValue on overflow. Positive overflows now yield long.MaxValue, negative overflows yield long.MinValue, and NaN yields 0. Updated Math.Floor and Math.Ceiling overflow tests to expect long.MaxValue accordingly.
