    I am using a RadNumericTextBox that needs to support up 5 digits before the decimal point and up to 15 digits (which i am planning on enforcing with an asp RegularExpressionValidator) after the decimal point (for example, 12345.123456789012345).  If I enter this number it gets rounded off to 12345.123456789011 when the control loses focus.

    If I enter 0.123456789012345 it stays as 0.123456789012345 when the control loses focus which is the desired behavior.

    This is the markup for the RadNumericTextBox



    telerik:RadNumericTextBox ID="radTXTValue" runat="server" Width="500px"><NumberFormat DecimalDigits="15" AllowRounding="false" /></telerik:RadNumericTextBox>


    Any help in resolving this will be appreciated.

    Hi John,

    I am afraid that you have reached a limitation in the Javascript. Try this to see it:

    parseFloat("12345.123456789012345") // will return 12345.123456789011

    You can try using a different type of textbox (e.g. RadTextBox) and handle (validate, etc) the numbers with custom code client-side and/or server-side.
