I know this may be the simplest question ever asked on Stack Overflow, but what is the regular expression for a decimal with a precision of 2?

Valid examples:

123.12
2
56754
92929292929292.12
0.21
3.1

Invalid examples:

12.1232
2.23332
e666.76

Sorry for the lame question, but for the life of me I haven't been able to find anyone that can help!

The decimal place may be option, and that integers may also be included.
