You can put your OR inside your regex:

use strict;
use warnings;
print "Enter the number to check if it is actually a number: ";
while (<STDIN>) {
    chomp;
    if (/^(\d+|\d+.\d+|-\d+|-\d+.\d+)$/) {
        print "Yes, it is a number\n";
    }
    else {
        print "No, it is not a number\n";
    }
    print "Give another input: ";
}
