FPL Abs bug

[ZhangHuan0407]

I think the result of FPL16.Abs cannot be negative.
Version: Nuget 30.1.1

// Decompile the code
public FPL16 Abs()
{
return Prescaled((N >= 0) ? N : (-N));
}

// Modified
public FPI16 Abs()
{
Int32 valueN = N;
if (valueN == MinValue.N)
valueN = MaxValue.N;
return Prescaled(valueN >= 0 ? valueN : -valueN);
}

// dotnet source code
https://referencesource.microsoft.com/#mscorlib/system/random.cs,61
They changed MinValue to MaxValue where they didn't expect an error.

System.Math.Abs throw exception, if value equal long.MinValue.

Console.WriteLine(Math.Abs(float.MinValue)); // 3.4028235E+38

Are fixed point and decimal more similar?
