# The AddUp Calculator

#### Complete.

AddUp 2 can perform conversions and calculations of all types and for all purposes: scientific, financial or computer-related.

It offers so many functions, units and scientific constants that a normal keypad could not contain enough buttons to cover them all. Instead, a variety of panels can be selected: they cover a wide range of functions you can choose from. Open the panels you require and keep the rest out of sight but still accessible as needed.

#### Flexible.

To provide flexibility, AddUp 2 uses a work area that behaves like a regular text editor. You type directly in this area to enter your calculations. Results are shown in this same area so you can use them directly for the next calculation. In fact, you don't need to use buttons at all, even though they can be convenient to have.

Nothing complicated is needed to convert measurement units: just use the "->" operator. Convert 500 grams to pounds with the expression 500 grams -> lbs. Convert nine inches to centimeters with 9 inches -> centimeters. It can hardly be simpler.

##### It's quick,affordable,fair.

Date and time operations are supported and flexible. Calculate using dates and/or times, separately or together. Convert into days or hours or years or any time unit. Add time periods to a date or subtract from a time of day. For example, calculate the number of weeks between two dates:

([2010-01-15] - [1996-06-30]) -> weeks = 707

Flexibility extends to the type of numeric expressions you can enter. Use normal numbers like "12.345", scientific numbers like "1.234e+5", fractional numbers like "1 3/4", even more complicated expressions like "1 3/4 sin(30 deg)". It's all understood. You can also express values in numeric bases other than 10 simply by adding the base as a prefix. You can also use complex numbers. You can also do more!

It is not possible to fully describe on one page all the features that are available to you. But the complete software documentation is included with the product. You can read a short overview here. You can also get more details here, a page dedicated to AddUp 2.

Of course, the best way to know what AddUp 2 can do is to try it for yourself. A help file is included that contains all the documentation provided in the above links. Go ahead, download and try it!
