C# Short Error: Negating the minimum value of a twos complement number is invalid

Question

I have been encountering this error for my project, which involves working with Digital Audio Signals.

So I have been getting the amplitude values and recently encou

Answer 1

What value would you have it be? there is no 32768 in short - only 32767.

You could write your own method, of course:

public static short LossyAbs(short value)
{
    if(value >= 0) return value;
    if(value == short.MinValue) return short.MaxValue;
    return -value;
}

but this is lossy in that it sort-of loses a value. Perhaps a better idea is: don't use short.MinValue if you intend to (potentially) negate it. Limiting yourself to -32767 would make this go away.
