| 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.
