Numculator is a user-friendly, easy-to-use but powerful expression calculator. It allows you to calculate the whole expression, not just one operation at time. Don`t spent time on each operation - get the final calculation result immediately.

Pros: Numculator is a very much calculator looking calculator simulator. Usual arithmetic operations with memory based operations are available too. What adds power to the program is an expression evaluator that evaluates an expression that may contain mathematical operations and functions. Percentage calculations are there too. What would be particularly useful to programmers is its ability to calculate in binary, hex bases besides decimal numbers. One could mix the numbers in different bases. Some simple stat functions such as max and min are available that can simplify calculations. Date and times are another set of function that can get life complicated, yet the calculator does make it simple. It allows you to calculate the whole expression, not just one operation at time. The memory calculations can go to any depth as there’s the large computer memory backing it up. It is also possible to memorize complete expressions. Track calculation through calculation history. About 40 built-in skins will help you to personalize your Numculator that is the additional fun factor.

Transparency settings can make it completely opaque and on top of the screen or one can choose a transparency level that is most comfortable. English & Russian language interfaces are supported. Windows versions starting from Windows 98/ME to Vista supports the application.
