Because '.' is special to preg, this expression ALSO matches:
12a25
5z43
7a
[aside]
Engineer: 7A, please.
Davey: What number, please?
Band: 7A!
Davey: All right, okay, just cuz I'm short
[/aside]
This might (or might not) do it:
/^[0-9]{1,3}(\\.[0-9]{1,2})?$/
The \\ is there so that PHP will turn it into \, and then you have \.
in the regular expression which the PRCE will interpret as "the
literal character known as 'dot'" instead of "any old character at
all"
