Sorry, I meant GMP number arithmetic with normal operators/math functions/ type evaluation functions is better to be considered as EXPERIMENTAL. It lacks GMP float support and many function won't work as it should be. (If we consider GMP number as "number" in PHP) It's safe to note GMP number arithmetic as EXPERIMENTAL and resolve issues.
