    Some months ago I had this working just fine!

    Suddenly have developed amnesia on how to use the DIV Operator and end up with a decimal number.

    As in 32767/32767=1

        32767/22222=1.474529

    22222/32767=.6781823

    I have tried every combination of data type: INT, WORD, REAL you name it.

    I can only ever end up with a 1 or a 0.

    IN1 and IN2 are Presently WORD at %IW0 and %IW2

    Can anyone refresh my memory?

    Hi,

    try this.

    FUNCTION DIVI : REAL
VAR_INPUT
  IN1: WORD;
  IN2: WORD;
END_VAR
VAR
END_VAR
DIVI := WORD_TO_REAL(IN1) / WORD_TO_REAL(IN2);

    regards Nitro

    Thank you for the quick reply.

    Issue is solved.

    I had declared IN1 AT %IW0: REAL;

    Went over this 100 times. Turns out I had a corrupt

    version.

    Started a new one, everything's fine.
