Heh, talk about a bit off topic. Anyway, I'm up for a quick challenge:
McVeigh:~% ./foo
3.0 3.2 3.4 3.6 3.8 4.0 4.2 4.4 4.6 4.8 5.0 5.2
Attached is the code (all 16 lines)
JE
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main(void)
{
float f;
float min = 3.141592, max = 5.003;
/* float min = -3.0308, max = -2.964; */
for(f = min - fmod(min, 0.2); f < (max + 0.2); f += 0.2)
printf("%.1f ", f);
printf("\n");
}
