HTML5 Input type number removes leading zero on IOS

Input type number is a new attribute for input field in HTML5. In HTML5, you can have a Input type number field as a spinner which have up and down arrows at the right of the text box. This will help to increase or decrease the number value. When we use type=”number”, we can also use patterns for the values. Numeric input fields can take additional attributes “min” and “step”, which constrain the range of values allowed in your input. The “min” attribute is fairly obvious: it’s the minimum value your number can be. The “step” attribute is less intuitive: by playing with different values, you would most likely work out that it controls the increase/decrease when clicking the up/down buttons on the field. If you input the number 1 and click the up arrow, it will increase to 2.
