InputNumber: maxFractionDigits default is 0 and the documentation says it's 3

[IlyaSemenov]

Describe the bug

InputNumber's maxFractionDigits documentation says: "the default for plain number formatting is the larger of minimumFractionDigits and 3;".

This is however clearly not true. <InputNumber> will not accept any fractional numbers unless maxFractionDigits is specifically set to something.

Steps to reproduce the behavior

1. Add <InputNumber v-model="value" />
2. Type 123.456 - it won't accept any fractional numbers

Expected behavior

It should work according to the documentation. Either allow 3 fractional digits by default, or the documentation should be updated to reflect the current default of 0.

The default value for maxFractionDigits is "null" as seen in the "Default" column of the API. The section you quote references the formatting of the value option, not the allowed input. If you have e.g. '5.12341' in your model value and enable format it will only show '5.123' by default and only more if you increase the maxFractionalDigits parameter.
See here for an example: https://codesandbox.io/p/devbox/primevue-inputnumber-decimals-forked-xkljjv?workspaceId=5ecc5d0e-e789-4dbb-80ba-89addaa3bd1f

So by default it will format 5.12341 as 5.123 but will only allow to change it to 4 or 6, correct? I agree that I misinterpreted the documentation but still the current behavior is a bit odd.
