long double literal

[Ioannis Vranos]

Do we designate a long double literal using an L after a floating point
literal, in the style:


long double d= 543.4545L;

Yes, L or l (lower-case L) can be used.

Both apply to C90/C95?

Unless it got revoked in C95 ;-) I pulled the information from C89.

OK, thanks. AFAIK, C95 didn't revoke anything, bug fixes and 3 new
standard header files in summary.

I have used a lowercase l for this.

I have used a lowercase l for this.

That's not a great idea, given that l and 1 look very very similar in
many fonts commonly used for viewing program sources.

Others agree with you (including me).

Yeah, but to go to Ubuntu, it must have caused brain damage when it
did.

Well, that is one of the known prime effects of Vista. It is
simply the culmination of Microsoft efforts so far.
