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

in C/C++

RE: casting

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.

RE: casting

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

 will give you an integer between 0 and 99.

"If you think you're too small to make a difference, try spending a night in a closed tent with a mosquito."

RE: casting

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

Will give you an integer between 0 and 100.

Just thought you might like to know that.

RE: casting

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

 keep the rudder amid ship and beware the odd typo
