casting

How do cast a float number( 1.234) to an integer (1)???

like
a=(int)1.234
in C/C++

One more thing, all this is caused by the function rand, I need it to return me an integer random number, and I get a float number.

So if there is anyway to random an integer, please tell me.

Hi dafoki,

You nearly had it by just copying the C++ code actually, try:

a=int(1.234);

[tt]
$a = int ((rand) * 100);
[/tt]
will give you an integer between 0 and 99.

[vcherubini]

$a = int ((rand) * 100) + 1;

Will give you an integer between 0 and 100.

Just thought you might like to know that.

additionally,
be aware that there is no 'real' casting in Perl like there is in other languages that type their vars. Once you have an integer in $a, there is nothing to keep you from sticking a float in again.

$a = int(3.2); # now $a is 3
$a = $a/2; # now $a is 1.5
