If you have PHP lower than 4.2 you can simulate the behaviour:
function is_infinite($value) {
return (substr("$value",-3) == "INF");
}
(tested on php 4.1.2)
is_infiniteDescriptionbool is_infinite ( float val )Returns TRUE if val is infinite (positive or negative), like the result of log(0) or any value too big to fit into a float on this platform. See also is_finite() and is_nan().
