mmh, I forgot all ";" and this don't go

much better like this: 

...
print "enter a number: \n";
my $num = <STDIN>;
if ($num !~/^[+-]?\d+$/){
print "this is not a number\n please type a number\n";
}
else {print "your number is $num\n"}
...

Update: my $num = int(<STDIN>); thus, 12.45 now is a number

ups... not so good idea,

enter a number: dfr34

your number is 0
