Gerhard, Negating an unsigned_integer that is not zero is like taking the square root from a negative value, or dividing an integer by zero: an exception is thrown. We are dealing with numeric classes here. Regards, Maarten. "Gerhard Wesp" <gwesp@google.com> wrote in message news:20060526144945.GG7522@google.com...

Negating an unsigned integer with value zero is very legitimate.
But the value may be non-zero.
E.g.,
unsigned_integer i = 4711; i.negate(); // i == ??
Having a method that is only defined, but a no-op, in the trivial case defies the purpose of having a method.
