Restrict an user to certain decimal points


I need to restrict a decimal property to 2 decimals (For ex; User should not be able to enter after 2.12). I tried using pyDecimalPrecision in property but that is not working as expected. It is rouding off to highest number.

Can any one know the exact solution on how to prevent user after entering two numbers after decimal.

You can use integer,number or currency control and give decimal places 2 in read only format in presentation tab and enable checkbox "Display value using read-only formatting" .Using this user can enter any number like 23.2345 but once user leave focus it will get converted to 23.23 automatically.

Thank you for posting your question.

The functionality of "pyDecimalPrecision" Qualifier is to round of to the mentioned places.

This is achieved by passing the precision parameter to the "Decimal" control as below.

It is not designed to restrict to the user from entering after mentioned value.

Kindly follow the below steps to achieve your requirement.

1. Open the "UserWorkForm" and add the below script.

$('#DecimalProp2').on('input', function () {
        this.value = this.value.match(/^\d+\.?\d{0,2}/);

2. In the place of "DecimalProp2" you should add the element id of your property. You can find that using browser debugger tool as below.

I have tested the javascript code it work like if i entered 12.4566 it returns 12.45

but my requirement is it does not allow to enter thrid number after decimal.

ex:12.45 after 5 if enter some thing it does not take input.

The above code I provided will not allow user to enter after two decimal values.

In the UserWorkForm replace the DecimalProp2 with your property ID.

This is working fine at my end.

Hi Parusharam,

UserWorkForm is a HTML Fragment rule belonging to Pega-UIEngine ruleset.

You can add the script in that rule.

Try this. 

<script type = "text/javascript" >
    document.getElementById("Prop").onkeypress = function(event) {
        var charCode = document.getElementById("Prop").value.toString();
        if (charCode.includes(".")) {
            var numb = charCode.split(".")[1];
            if (numb != null && numb.length > 1) {
                alert("Only 2 decimal places allowed");
                return false;

I tried this at my end and it seems to be working.

Also, add a Null check before this, so that we do not get the console error messages in Developer tools for the screen which does not have this property.

Please find the attached code.
