Since numbers using exponents without also using decimal points are rare 
in my code base, I've decided to experiment with numbers like 1e6 being 
integer constants rather that floats. (This is IN my language.)

I've done the change in one compiler and will see how well it works. It 
will only be for base 10.

I'd find it useful in C too, but in my compiler, I'd need to find a way 
of making it optional, so that it works that way in programs I write, 
and is conforming for anything else.

(Or I maybe I'll just say to hell with it, and make that change anyway. 
I'm fed up with laboriously counting zeros.)
