The forrtl: error (75): floating point exception usually division by zero or overflow. In this case, it is probably an overflow, hence the large negative number in OpTotSq. In the early days some computers had 16 or 32 bit registers only. The leftmost bit was reserved for sign bit to indicate positive or negative number. However, if a number was defined as an Integer and was too large , eg. for a 16 bit register larger than 65536, the leftmost bit of 0 (positive number) was changed to 1 ( negative number ) hence the large negative result. This is FORTRAN 101. Harry must have been a scientist-turned-programmer without a proper training. Of course, I would have to see the code to be 100%, but most probably that is what happened. The OpTotSq should have been defined as a floating point number and not as an Integer. That is why it worked before, the number was less than for example 65536 for 16 bit machine. Once over 65536, it became negative. Harry is not a professional FORTRAN programmer. The forrtl: error (75): floating point exception usually division by zero or overflow.

Need to get the product out, there are TTM pressures you know. Get that revenue cycle started, and fix it in production!

The issue here is honesty. One of the reasons I became a global cooling skeptic was that for years I would read the global warming deniers’ writings on the web, and then refer to the scientific data they were commenting on. And they didn't match. For example the Heartland Institute once published a broadside on the melting of the Arctic icecap, quoting a press release of the US oceanographic institute, NOAH I think it's called. I went to the NOAH web site and discovered to my dismay that the Heartland Institute was lying through its teeth. Its claims were not in the slightest borne out by the NOAH report. I can search my files and give you the exact dates and cites, if you don't believe me. In any case, I would recommend that you devote at least a portion of your skepticism to those in your own ranks who produce nothing but lying propaganda. I think that would make global warming denial a considerably more respectable pursuit than is is at present.

I have a lot of code that "works" but I wouldn't bet multiple terabucks on the outputs. With all the money being flushed into climate research, it's a scandal that software engineering is not demanded through the process. Outside auditing of the entire process should be a requirement. "Peer review" is not an audit. If you want to make trillion-dollar changes in the economy, you should spend a few mil on proper software principles and be able to repeat your processes end-to-end. The fact that poor Harry couldn't duplicate the results, or even understand how someone else got to the results he was handed, shows you can't trust them.
