Errant bitwise operation on 64 bit core ...

[hmm213]

I'm doing a php bitwise assignment operation on a 32 bit system with a 64 bit core. The problem is that the result comes out wrong on my system with PHP. The result comes out fine when performed on a 32bit system with a 32bit core.

 

JS handles the operation fine on both systems. I guess the JS interpreter is more comprehensive than the PHP one then ?

 

$e = (double) -4738698913; $e = ($e ^ (43814)) + 0.001; var_dump( ( (float) $e ) );

 

The result I'm looking for is ... -443704711

 

How can I get the proper result on a 64 bit core ?

 

Thanks
