When entering a number with decimals in a Native NumericTextBox with a format it rounds up the number if you enter more decimals than the format allows. In this Stackblitz project you can see this behavior.
In the Wrapper NumericTextBox it is possible to add a round property with the value false which prevents the rounding of decimal numbers. Instead of rounding it truncates the number. By my knowledge and what I can find in the Vue documentation this property isn't available in the Native NumericTextBox.
Proposed solution
Add round property with related logic to the native component.
