UNSIGNED_ZERO | Constant (Pseudo-constant) |
| math.h, timath.h |
| #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.
