Working on this option now. After looking at it, removing the binary operator- seems rather harsh... if you know that a number is larger than what you're subtracting from it, it would just be irritating. But I'll definitely add the absdiff function (maybe named "difference"?), then the developer using the library can decide which to use for himself.
Why not just go the simple route and define it as "undefined behaviour", then just pretend they will never get a negative number and let your math functions choke on it as they wish, making invalid values, dividing by zero, whatever, it is "undefined behaviour" after all.
For something as simple and common as subtraction, that seems rather harsh too. But in any case, the problem is solved; when you declare an integer to be unsigned, you also have to tell it how to handle operations that result in negative numbers. - -- Chad Nelson Oak Circle Software, Inc. * * * -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkw3MCoACgkQp9x9jeZ9/wQ8JACgijcm+lyLXn5UJf3z/L/Bd3lm xyUAoIl6EqgCW3FsfR8ldjhTVo/EgEfj =Wxp+ -----END PGP SIGNATURE-----
