I'm sorry, I should have been more precise. Section 8.3.3.3 of the ISO
spec defines both fixed- and floating-point numeric literals.
"A fixed-point numeric literal is a character-string whose
characters are selected from the digits '0' through '9', the plus sign,
the minus sign, and the decimal point. The implementor shall allow for
fixed-point numeric literals of 1 through 31 digits in length."
A floating-point numeric literal is signified by an 'E' between two
fixed-point literals, where the exponent may have no more than 4
digits, and no decimal point.
What exactly that implies for constant compile-time expressions, now
that fixed-point computation is available, I'm not sure. I just want
to clarify what ISO says, to avoid any confusion.
