is_finite()

bool is_finite ( float $val )

Description

is_finite() checks whether $val is a legal finite on this platform

※ available F/W version : all

Parameters

• $val - the value to check

Return values

TRUE if $val is a legal finite number within the allowed range for a PHPoC float on this platform, FALSE otherwise
