UNSIGNED_ZERO | Constant (Pseudo-constant) |

#define UNSIGNED_ZERO (0.) |
Represents an infinitely small quantity with indeterminate sign.
TIOS makes a difference between three types of zeros. UNSIGNED_ZERO
is "ordinary" zero,
i.e. infinitely small quantity with indeterminate sign. It is identical to
ZERO. Dividing any finite non-zero number by UNSIGNED_ZERO
will produce
UNSIGNED_INF.
All kind of zeros are equal when comparing using comparison operators or fcmp. To check
whether a value is an unsigned zero, use is_uzero.
