I was getting a whole bunch of floating point errors when I was mapping out a soft-variable (confidence, success, etc) model, and I didn't discover why till just this week.

When you divide something by time, and time is zero, you will get a floating point error. Fix the initial time to a number. Or what you can do is find a better way of representing your equations using flows.

Hope it helps!

You could also formulate it using the XIDZ or ZIDZ macro in vensim
