RegEx needed to match number to exactly two decimal places

Question

I need some regex that will match only numbers that are decimal to two places. For example:

• 123 = No match
• 12.123 = No match
• 12.34 = Match

Answer 1

You can also try Regular Expression

^\d+(\.\d{1,2})?$

or
var regexp = /^\d+\.\d{0,2}$/;

// returns true
regexp.test('10.5')

or
[0-9]{2}.[0-9]{2}

or
^[0-9]\d{0,9}(\.\d{1,3})?%?$

or
^\d{1,3}(\.\d{0,2})?$
