is_inf |
Function (ROM Call 0x2FF) |
Checks whether the argument is an infinite number.
is_inf returns TRUE if x is an infinite number
(i.e. UNSIGNED_INF, POSITIVE_INF
or NEGATIVE_INF), else returns FALSE.
Infinite values are produced when the result is unbounded (for example dividing by
zero), or in case of overflow. This function is an alias for TIOS function
originally called is_float_infinity.
