printf trying to format numbers....

**Dragonslayre** · 07-07-2007

Hi,

I think this explains what I'm trying to do:

Code:

for(i=0;i<5;i++) {
		printf("float j=%%d.%df\n",i,i,j);
	}

I don't wish to hard code the way of formatting a float, but what I've got doesn't work, any solutions to this???

You mean something like...:

Code:

#include <stdio.h>

int main(void)
{
  int i;

  for(i = 0;i < 5;++i)
    printf("&#37;*.*f\n", i, i, 1.5f);

  return 0;
}

?

My output:

Code:

itsme@dreams:~/C$ ./varformat
2
1.5
1.50
1.500
1.5000
itsme@dreams:~/C$
