You don't state this clearly, but it seems that you are treating this "decimal" value more like a version number, in the format [number].[number]. I know you already gave yourself credit for the correct answer, but I have to disagree.

First of all, your regex [\d]{1,}\.[\d][0-3]{1} has some extraneous syntax. Here's the clean equivalent: \d+\.\d[0-3]

It will incorrectly match these values:
1.00, 1.20, 1.21, 1.22, 1.73, 1.90, ...
It will incorrectly miss these values:
1.1, 1.2, 1.3, ...

This is what you really want:
^\d+\.(0?[1-9]|1[0-3])$

it is not allowing integers. i want a regular expression which allows positive integers and decimal numbers having two decimal points whose values ranges from 0-13
