#include <stdio.h>



#define NUMBER 16777252.0



int main(){

 for(float i = NUMBER; i < NUMBER + 1; ++i) printf("%f\n", i);

 return 0;

}

does this program terminate?

No.

OP Speaking: complete demonstration code here, runs on a GNU/Linux (it should be mostly POSIX compliant).

Seemingly useless, but the algorithm allows to build a simple sprintf-like function for integers, without having the whole stdlib

because snprintf is so bloated amirite? brb going to develop anonix.

...just think about embedded systems. A few kilobytes of memory available and an operating system without stdlib... what would you do? Go.

most of the time when people use snprintf, they really want to use asprintf instead... too bad it's not in the C standard, even though it is supported by just about every widely used libc.

Most of the time when people post into a thread in sage and talking about a non-stardard pieces of code, they really want to troll.

Enjoy your failure.

They are still using CVS! What a lame.

at least it's not slow as fuck like that darcs and git and whatever else the kiddies are using these days.

Such a jerk. DVCS are the future. You are old stuff, faggot.

You even said it's running on GNAA/Linux
Anyway, this task is trivial, bro. Even if you don't want to write this little procedure yourself, you'll just c/p it from libc's itoa. I'm not sure why you posted this code on our nice /prog/ board. bro.

if by "distributed" you mean slow as fuck because it downloads over 9000 old versions of the code, then yes. also, enjoy your merge conflicts.

CVS is distributed under a Free GNU license and can be obtained quite readily. Proceed here for instructions on using UD6/CMtool and Uniface with CVS.

Clearly you don't know that GIT can also be employed as central repository. While everyone maintains their private copy, all changes are uploaded exclusively to the main hub, so in this respect it acts very similar to SVN while still providing a better overall source control experience to the programmer.
