Much easier to figure out, don’t you think?

(In source code, it would also be useful to use 1e9 or 1e12, unfortunately those normally yield floating point values. I can't do much about that in C, but I will see what can be done with my own stuff.)

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.)
