title: Force number input to have two decimal places and always show two decimals in React
body: <p>I want to have an input field that always limits input to two decimal places but also displays two decimal places,</p>
  
  <p>I know this is a follow on to this question:</p>
  
  <p><a href="https://stackoverflow.com/questions/43543817/force-number-input-to-have-two-decimal-places-and-only-two][1]">Force number input to have two decimal places and ONLY two</a></p>
  
  <p>But when I implement this in React, it doesn't format to 2 decimal places, if say the number is 3. It is as if it is ignoring the step prop.</p>
