 Updated on Sep 19, 2010I did a little investigating, and I am concerned about you downloading version 3.01. At this time I advise not doing so. You might want to check out: ESBCalc or graphCalc
Excellent!

Very nice, slick calculator. The tape works very well - I tried a lot of other calculators before I found a calculator I was happy with. It could do with some skins to liven it up.

Developer’s Description

Manage your calculations and check them on a scrolling tape.

Showcalc is a Windows calculator with a scrolling tape so you can check your work. It has a huge range of functions including scientific, tax, and a full-featured unit conversion facility. The scrolling tape display can be customized to your needs. You can change the tape's fonts and colors and numbers can be shown in different formats including your local currency. Also, for accountants, negative totals can be shown in red. If you get a calculation wrong, you don't have to enter the whole thing again - you can go back through the calculation using the Previous and 'Next' keys, enter the correct number and 'replay' the calculation. You can also hide the tape and/or scientific functions to give the calculator a slimmer profile. Additionally, for people with vision difficulties, Showcalc has a 'zoom' feature that lets you double the size of the calculator.
