Nothing surprising about that.  That's how floating point numbers
behave, if you don't round them to a more sensible number of digits on
display.

And what makes you think that's a problem?  Absense of any number is
clearly not valid, and you've just disallowed invalid values, right?
Just type '0' instead of <Backspace>, and I think it'll work.

Well, as the saying goes: don't do that, then.  I.e. if you use masks
like that, make sure you provide an initial value that matches the
mask.
