Note: Our NumericTextBox component uses the JavaScript Number object, which loses decimals after the 16th digit, so it behaves like a normal TextBox. You can find more information about Number objects in the following documentation. To overcome this limitation, define the max value of the NumericTextBox to be less than a 16-digit number.
