Issue with HTML Input for Floating-Point Annotated value

[M. Torkashvand]

What happened?

The HTML type="number" input strips the decimal point from our float type (for example: longitude coordinates), leading to incorrect data handling for floating-point numbers.

Steps to Reproduce:

define an annotated field

def validate_longitude(v: float) -> float:
     return v

LongitudeCoordinate = Annotated[
    float,
    AfterValidator(validate_longitude),
    Doc(
        "A longitude coordinate, modeled as a string. "
        "The coordinate must match the format conforming to the longitude "
        "range of -180 to +180 degrees. It can be a floating-point number or an integer. "
        "Valid examples: 40.7128, -74.0060, 180, -180, 0."
    ),
]

then in the generated HTML form enter a floating-point number in the longitude input field.
Observe that the decimal point is removed or rounded.

Expected Behavior:
Users should be able to input longitude coordinates with decimal precision.

Hi Wouter
We found a workaround for this in our side by changing the field to string and writing some validations but the field was really float!
so I would say if you have time you can have a look to this issue

Ok, I will discuss this with the developers. We are investigating to move the dynamic form instead of uniforms, so we might consider fixing in the new dynamic forms (might take a while).
