Where to find Complex Number Calculators
© 2001 by Karl Hahn
There are some publicly available calculator programs that will do complex arithmetic. This page tells you how to download two of them.
You can download a calculator that runs under Microsoft Windows from the SimTel archive. Get to the SimTel page for this calculator by clicking here. Then click where it says, "calcz10.zip" to start the download. Unpack the archive to a folder of your choice, then from your Windows Explorer, click on CALCULAT.EXE to start the program. You will probably have to read the help screen to get started. Note that this calculator does 100 digit accuracy calculations, which makes for a small-print display.
Another calculator that does complex arithmetic is Desk Reference Scientific Calculator. It does a lot more as well, including having page after page of useful data that you might use doing physics or chemistry problems. Unfortunately it was created during the DOS era, and runs under a DOS emulator screen. You will need to download the DRSC archive from SimTel by clicking here and then clicking where it says, "drsc104.zip" to start the download. To make this thing work under Microsoft Windows, you also have to get some accessory files. Click here (you might have to shift-click) to get that Windows accessory archive. Open the accessories archive and read the readme.txt file carefully before continuing. Also, since DRSC was published there was an update to one of its chemistry data pages to include molecular weights of common inorganic compounds. If you want to get that update, click here (again you might have to shift-click) to download it. Expand its contents (CH_BOOK.HLP and CH_BOOK.BK) into the same folder you installed Desk Reference Scientific Calculator into (it will overwrite the old versions of the CH_BOOK.HLP and CH_BOOK.BK).
If you downloaded the update before 6-Sep-01, then download it again. The update from before that date was incorrect.
