Precision question
Posted: Fri May 12, 2017 10:35 pm
I've attached a simple model that replicates an issue I'm having in a larger model. It's got three stocks, initialized to 315400, 5810, and 600 units. There's a Total variable that does what it implies.
However, it says the total is 321800, while my calculator and my brain say it should be 321810.
Is that the single-precision DLL at work, or is there something else going on? I'm running DSS 6.4E (x32).
As far as policy goes, this is a non-issue. I found it as part of a mass balance check to make it easy to see that I was initializing stocks to get the desired total. I knew the total I wanted (321800), and so I thought the initialization was working until I added the numbers manually.
Thanks,
Bill
