Re^5: number array with space

[2teez]

See looks_like_number in Scalar::Util like thus:

use Scalar::Util qw(looks_like_number);

 for(qw(1 perl 25 monks)){
   looks_like_number $_ ? print $_," is a Number",$/ 
                        : print $_," is not a Number",$/;
 }

Update:
Awooooshhhh! davido, beat me to it.....

Yeah, but I left out the example, which you thoughtfully provided. ...or I left it as an exercise for the reader to figure out. ;)

hey

what i want to do is that check whether the array cell has a number or not , if yes execute my block of code else not i.e.

 if( $array[$i] == number )
{
my block of code ;
}

Simply go for regex then:

if ($array[$i] =~ /\d+/){
    <your code>
}

[AnomalousMonk]

if ($array[$i] =~ /\d+/){
     <your code>
 }

But that matches non-numbers:

>perl -wMstrict -le
"print 'this is a number?!?' if 'x9x' =~ /\d+/;
"
this is a number?!?

Better to use  Scalar::Util::looks_like_number() (see this), which correctly identifies numbers like  '1.2' '1.2e3' '0e0', or if only decimal digits are acceptable, use the  /^\d+$/ regex (see this).
