> The precision is lost when converting double to string.
>     E.g:
>     $num= 3.1415926535897931;
>     $this->trans_->write(json_encode($num));    
>     The value will be '3.1415926535898' and some precision lost after format 
> operation.
>     But expected value should be '3.1415926535897931'.
>     Solution:
>     ini_set("precision",17);
>     $this->trans_->write(json_encode($num));
