How to limit the decimal point in a regex?

@elise_daugherty 

To limit the decimal point in a regex, you can use the following pattern:

d+.d{1,2}

This pattern will allow for one or two decimal places after the decimal point. Here's an explanation of the pattern:

• d+: Match one or more digits before the decimal point.
• .: Match a decimal point.
• d{1,2}: Match one or two digits after the decimal point.

You can adjust the {1,2} part of the pattern to match a different number of decimal places if needed.
