How can I check that the value assigned to $cell and $sector is numeric

I am just trying to clear this warning.
Argument "" isn't numeric in sprintf at ./rt_evdo_pcmd.pl line 139,<$FIN>
line 119503.
line 139 is from my program is below:
my $c_s = sprintf("%d_%d",$cell,$sector);
Why are you using sprintf for something you could do with string
interpolation:
my $c_s = "${cell}_$sector";
