Trouble with floor ()

[Robert Zeff]

I'm having trouble with ceil () & floor ().
This program returns the correct values on the first loop only.
On successive passes, floor() returns the same result as ceil().
I'm using a Tektronix 4301 (68020, UTEK & BSD4.3, 
GreenHills C compiler.)

#include <math.h>
main () {
  double value, ceil (), floor ();
  
  for (;;) {
    printf ("\nInput value: ");
    scanf ("%lf", &value);
    printf ("\nCeiling: %lf, Floor: %lf\n", ceil (value), floor (value));
  }
}

Anyone else having this problem on other hardware?
thanks,
