Error Pattern to match decimal number and interger


i've a code
if (($A && ((!($A =~ /^\d+$/)))))
 -- -- not a number
--- its number.

which matches for integer value, i need to modify that pattern where it matches decimal number with 2 decimal points and also integer value.
for eg: values 10, 10.00. 0.1, 1 , 3 must print successful . and numbers like
10.0000 0.0001, 01.111 and alphabets 11.ssasd should not accept.

Try regexp in this script:
use warnings;
use strict;

while ( <DATA> ) {
    printf "%s\n", $_ if /^\d+(?:\.\d{1,2})?$/;

Found this regx also

if (($A && ((!($A =~ /^\d+(\.\d{1,2})?$/)))))

which works for 2 decimal numbers and inegers.
