Re: Test if number is integer or float?

rui.mac...@gmail.com (Rui Maciel) — Sun, 14 Mar 2010 14:10:15 UT

As we are talking about a syntax used to represent numbers, I don't believe that there could
possibly be any ambiguity in this subject. It is pretty clear that, in this context, the
string "123.0" represents a floating point number while the string "123" represents an
integer.

I was trying to avoid that in hopes that somewhere some standard routine or even library was
able to do that job. Oh well, a parser it is then.
Thanks for the help,

Hello,
I have a lot differential equation and would solve
the problem with finite element method. Is there
any good open-source lib which I can use with
the boost ublas structures?
Thanks for help

And you have verified that if you write it in a straight-forward way,
(a) the compiler doesn't optimize it to perfection and (b) it *does*
take unacceptable long time?
But I'm not actually sure what the straightforward test would be. It
would be an interesting exercise. And you're right, if you know

I don't know, but my standard response to the constant stream of

disappears.

Re: is c++ requirement to cast pointers(like the one returned from malloc) redundant ?

Which (real-life) situations are that? Interfacing to C libraries
which use it: yes. I think I'd wrap such an API if I had to use it.
But other than that, I can't remember having used void* recently.

Re: Converting CHAR_MAX+1 to char?

b...@gmb.dk (Bo Persson) — Sun, 14 Mar 2010 11:37:40 UT

If we look at the type traits (C++0x), is_signed and is_unsigned are
defined for all arithmetic types, which includes plain char. There the
expression char(-1) < char(0) defines its signedness.

But that's C code, not C++.
Templates solves the problem of returning the proper type, as shown by
the new operator. That way you don't need the totsally unsafe implicit
casting.

* Chris Gordon-Smith:
Sure. That's almost a given. But we're not a point yet where there's even any
consensus about the simplest things.
Consider the C++ standard library's exception hierarchy. I haven't heard about
anyone who use those exception types as their names indicate. Yet very good
brains were involved in forming the standard library.

I would be interested to know whether there are any guidelines on this. It seems to me
that exceptions are often useful in cases where the program itself has done nothing
wrong, but something unusual has happened in its environment.
For example, 'out of memory', or a network error. If the program's users value
