ID: 55464 Updated by: cataphr...@php.net Reported by: zandor_zz at yahoo dot it Summary: differ is_float() from is_double() -Status: Open +Status: Bogus Type: Feature/Change Request Package: Variables related Operating System: any PHP Version: Irrelevant Block user comment: N Private report: N New Comment: There is only one floating point type in PHP -- it is named float, with "double" (and "real") as an alias and the underlying representation is a C double. Both is_float and is_double (and also is_real) test for this type. So the proposal makes no sense. As such, I'm closing this as bogus. What I think you actually wanted to suggest is introducing a new type with single precision. This would be a rather big change with no compelling advantages (the double can represent all the values the float can) and possible BC breaks. In any case, such a change would require extended discussion; see https://wiki.php.net/rfc Previous Comments: ------------------------------------------------------------------------ [2011-08-19 20:02:14] zandor_zz at yahoo dot it Description: ------------ It would be nice to differ the behavior of is_float() from is_double(). This situation is not consistent cause float and double do differ for different byte size. I have created a PHP class to handle advanced read/write operations on files and I crashed onto this ambiguous situation. Thus I wrote myself a workaround to solve this ambiguous situation. Then I suggest that it would be nice to rely on this feature in the standard PHP library. Test script: --------------- It is known from PHP standard documentation that is_double() is an alias of is_float(). ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55464&edit=1
