[ryangrosso-cl]

Environment

Vuetify Version: 4.1.3
Vue Version: 3.5.39
OS: Windows

Steps to reproduce

1. Using a v-number-input with precision null and the initial v-model set to 1234.1234.
2. Focus the input and click outside the input to unfocus
3. Both the VNumberInput displayed value and the underlying value are incorrect

Expected Behavior

Initial value is set to 1234.1234. After focusing and unfocusing the value is still 1234.1234.

Actual Behavior

On mount the value displayed in the UI is incorrectly showing 1234.123. The underlying value is correct 1234.1234.

After focusing and unfocusing the value becomes incorrect and the display value in the input UI remains incorrect as 1234.123.
