Blueprint Subtraction always returns 0

Hello,
i have some strange behavior when using the subtraction node:

the vector2d has X and Y setup at 30

when i use the subtraction,though the subtraction always returns 0.

Am i doing something wrong or this is a bug ?

thank you

Use a print string to put the values on the screen, what is shown at the pin in debugging may not be the actual value.

You are actually right, but due to another mistake i wasn’t viewing it correctly in the viewport.
I’m quite puzzled by the utility of a debugger that doesn’t show correct values though :confused:
Thank you
