How to validate decimal positions with Parsley or HTML5?

How can I validate an input to have an exact amount of decimals? For instance, if I want to validate a number to have 2 decimals then I want to validate as follow:

• 2.888 -> fails
• 2.8 -> fails
• 2 -> fails
• 2.88 -> validates

You could use the data-parsley-pattern attribute, and use a regular expression to match number to 2 decimal places:

data-parsley-pattern="^[0-9]*\.[0-9]{2}$"

Also, remember to add a required attribute to your tag.
