short is_transfinite (float x);

Checks whether the argument is a transfinite number.

is_transfinite returns TRUE if x is a transfinite number, else returns FALSE. Transfinite numbers are all infinite numbers (UNSIGNED_INF, POSITIVE_INF and NEGATIVE_INF) and NAN. This function is an alias for TIOS function originally called is_float_transfinite.
