RegEx to match a single digit followed by a “.” followed by another single digit

Question

I am trying to find the RegEx in use with the preg_match function for a single digit followed by a "." followed by a single digit.

Example:

3.3 valid 44.4 invalid but would capture 4.4 4.664 invalid but would capture 4.6

\\d{1,1}[\\.]{1}\\d{1,1}
