Steps to reproduce

Create input field with number, start the number with 0 and any other number, the input registered will be without the 0.

I'm aware that we can use string to make it work, but wanted to report the problem.

✔️ Expected Behavior

Certain numbers can start with 0, like Zip-code, this should be able to be included?

❌ Actual Behavior

0 is removed from the number.

Dify currently does not support leading zeros in number inputs. When a number input starts with a zero, the leading zero is stripped away. This behavior is due to how numerical strings are converted to integers or floats in the backend, which inherently removes leading zeros.

For cases like Zip-codes, where leading zeros are significant, using a string input type is the recommended workaround. This ensures that the leading zeros are preserved.

If you need further assistance or have more questions, feel free to ask!

The "Number" type variable will be converted to an integer or a float object in Python, so it cannot start with 0.
