| is_inf | Function (ROM Call 0x2FF)

AMS 1.01 or higher | math.h, timath.h

short is_inf (float x);

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.
