Sürüm Bilgisi

Sürüm: Açıklama
Since 4.0.6 The function will now return integer results if possible, before this it always returned a float result. For older versions, you may receive a bogus result for complex numbers.
Since 4.2.0 PHP stops to emit a warning if the value can't be computed, it will now silently return FALSE only.
