+ if (mv < 0 || ik_unit == IK_KELVIN)
printf("%jd", mv);
+ else if (ik_unit == IK_FAHRENHEIT)
+ printf("%.1fF",
+ (mv - 2732.0) * 9 / 50 + 32.0);
else
printf("%.1fC", (mv - 2732.0) / 10);
Ah, so then units are in tenths of a degree Kelvin? Any special reason
to prefer not showing it with printf("%.1fK", mv / 10); like the others?
cheers, Ian (possibly jumping in out of my depth :)
