Dify version

1.10.0-rc1

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

  1. Create a workflow with an if-else node
  2. Add a condition: integer variable 0 compared with string "0.95" using operator <=
  3. The condition incorrectly evaluates to False instead of True
Image

✔️ Expected Behavior

When comparing numeric values, the system should correctly convert types:

  • 0 <= "0.95" should evaluate to True
  • 1 >= "0.95" should evaluate to True
  • 1.1 >= "0.95" should evaluate to True

❌ Actual Behavior

The comparison fails because when comparing an integer with a float string, the code converts the string to integer (losing precision). For example, "0.95" becomes 0, so 0 <= 0 evaluates incorrectly.
