UltimaCalc (30-day feature-limited demo) falls into that group of "If you realize what it does, you most likely desire it." I was expectant something like the Windows calculator device with hardly any dozen additional buttons; what I got was an influential arithmetical implement with a very simple interface.

UltimaCalc performs complicated arithmetical procedures:

UltimaCalc very greatly assumes you know what you're doing; know what you desire, as well as wish for a program which gets out of the way and gives you reply. The main interface consists of two text boxes; one where you type equations, as well as one which shows you the result. You can sort easy things like "2+2" and get "4", or you can sort extremely lengthy with difficult formulae. The results can be logged to textbook files, which you can identify. There is no "history" utility; every equation you sort erases the one before, but, and this is essential, one variables you describe maintain their value. So you can type "a=2", then type "b=4*a", as well as both "a" and "b" will be around for the leftovers of the session for you to employ in more formulae. This is very good for letting you plug values into equations.

As well to the mathematics, UltimaCalc has a digit of extra tools, for example one which will speedily explain trigonometry problems a program to find the roots of polynomials; answer linear as well as non-linear equations, with much more. This program seems perfect for group who require doing a lot of fast, but complicated, calculations as part of several other tasks, for example engineers or else architects.

The interface is very simple, and it is frequently the case that one window must be closed previous to focus can be shifted to one more, though this is not always clear. Some things which should have default course, such as the log file, must be lay down by the user before they can be used. Error messages are not always supportive, as well as the trial version, in addition to being time-limited, pops up "Buy now!" reminders with significant occurrence and is also inadequate in functionality, though not to the size that evaluating the program is made more complex. (As, the trial allows only four equations for simultaneous linear equations, the full version up to ten).

If you use a lot of your day doing math that requests more than a calculator--but less than a successful tool such as Mathematical--UltimaCalc is attraction evaluating. UltimaCalc is extremely insubstantial in its system demands, making it preferable to sacking up Excel for these sorts of things.
