Numeric textbox changing value automatically to 10 000 000 000 000 000, 00 when enter 9 999 999 999 999 999, 99

We are facing an issue with Kendo numeric textbox.

In numeric textbox, when user tries to enter the value as “9 999 999 999 999 999, 99”, it automatically converts to “10 000 000 000 000 000, 00”.
The converted value is passed to model also.
We have an requirement to restrict user to allow enter values up to “9 999 999 999 999 999, 99”.

Kindly check and provide your feedback.

Hello Fady,

The behavior that you are describing is related to the JavaScript Number object, used by the NumericTextBox, which loses precision after 16 digits. You can test the following simple scenario, which will demonstrate the same result:

var number = -9999999999999999.99;
alert(number);

You could find detailed information on the Number object in the following link:

Thanks for the reply.

 

Is there any solution available to this issue?

Hi Fady,

Since the widget is using the JavaScript Number object, there is no workaround that could be used. The only thing that could be suggested for your requirement is to use a standard input that will allow the user to enter any string value that you could then handle manually.
