# casting

## casting

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

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

### RE: casting

(OP)
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

Hi dafoki,

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

a=int(1.234);

$a = int ((rand) * 100); will give you an integer between 0 and 99. "If you think you're too small to make a difference, try spending a night in a closed tent with a mosquito." ### RE: casting$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
