Re: [Bug-gsl] GSL_NEGZERO

[Gerard Jungman]

Sorry, I read the output wrong. Just did it for myself.
What the hell??


#include <stdio.h>

#define GENERIC_NEGZERO (-0)
#define LESS_GENERIC_NEGZERO (-0.0)

int main () {
  double x = -0.0;
  double y = GENERIC_NEGZERO;
  double z = LESS_GENERIC_NEGZERO;
  printf("%a %a %a %a\n", 0.0, x, y, z);

  return 0;
}

$./a.out 
0x0p+0 -0x0p+0 0x0p+0 -0x0p+0
