Bug description: rand() gives range warnings over 15 bits
rand() should work on int, which is about 2 billion. But i get
Warning: rand(): Invalid range: 1000000..1032768 in /tmp/apa2/htdocs/admin/tst.php3 on line 1
For this code:
<? print rand (1000000, 1032768); ?>
(a result is given anyway)
Not the size, but the difference seems to matter: If it exceeds 2^15-1, the warning comes up:
<? print rand (1000000, 1032767); ?>
produces only a result
sizeof(int) really is 4.
So i don't think it's my fault.
