Hi,
I tried the following piece of code which is not working.

$v=1;
$f=!($v);
print "**$f**\n";

[download]

The Output is ****. However, if i do

$v=0;
$f=!($v);
print "**$f**\n";

[download]

Output is **1**.

It looks like !(1) does not return zero whereas !(0) indeed returns 1. What can be the reason behind this and what should i do to get 0 from 1 by logical not.

thanks
nghosh
