Hi Tjerk,

I forgot PHP's GMP implementation does not support float. Thanks.
And I was expecting

[yohgaki@dev php-src]$ ./php-bin -d error_reporting=-1 -r
'$f=2.2;$v=gmp_init($f); var_dump($v);'

Warning: gmp_init(): Unable to convert variable to GMP - wrong type in
Command line code on line 1
bool(false)

this kind of behavior for literal, too. ;)

Why is PHP not raising error for float literal?
