FNA FNA is a multi-function scientific calculator and unit conversion utility. Four modes of operation (statistics, trigonometry, base-n, and unit conversion). Convert units of Acceleration, Angle, Area, Density, Energy, Force, Fuel Efficiency, Length, Mass/Weight, Power, Pressure, Speed, Temperature, Time, Torque and Volume. Perform complex mathematical calculations using such operations as factorial, gamma, combinations, permutations, logarithms, standard and hyperbolic trigonometric functions, and base-n conversions and logical operations. Store and recall even between sessions with 26 separate memory registers. Special calculations include heat index, wind chill and days between dates. Built-in references now include Periodic Table of Elements with extensive chemical data, drop-down conversions for metric prefixes, counting units and atomic weights. Version 1.31a now has support for German, Dutch, Swedish, Italian and Portuguese keyboards.

Inplace Calculator is more than just a simple computing utility. It automatically extracts/inserts digits or expressions from/to any documents, so you don't have to copy/paste data or type it manually in. Simply place a cursor over data you want to input or select an expression and it gets automatically inserted. Perform necessary calculations and the result is ready for the output back inside the document. Plus, the program converts 120+ time, length, volume, weight and other measurement units, comes with conversion rates for 150+ currencies updated automatically and works as a mortgage calculator. And it does all that not only inside own program interface, but rather inside any document or application you need, freeing you of unnecessary mouse movements and keystrokes. Using Inplace Calculator, you can do your work in a fraction of time it used to take you before you downloaded this awesome program. Inplace Calculator comes with scientific/engineering calculator features, like evolution, involution and exponential calculation, computation of logarithms, trigonometric functions, and features a handy expression evaluator that helps you avoid mistakes, misprints and errors. The calculation history feature displays a complete list of data entered and calculations performed, so that you can always come back and look up the results you need. Are you impressed? Then add eye-candy interface, easy setup, comprehensive Quick Start Guide and free trial to understand why the experts consider Inplace Calculator the best calculator software currently available on the Internet.

Usually software calculators imitate hardware calculators. It allows Users the ability to quickly start their work with a new program, since the user already knows how to use their hardware calculator. But with this approach, in regards to the design of software calculators, it inherits all of the defects of hardware calculators. For example:
- Every number, operator, or function that is inputted separately at that priority must be kept in mind. For example, if a calculation is made in ordinary calculator expression 2+2*2 then result is 8, but if 2*2+2 is calculated, then the result is 6. Certainly 2+2*2 and 2*2+2 is equivalent. This is how ordinary calculators provoke errors.
- The window of the program is painted in the form of a device with many unnecessary buttons, and a single indicator for input and output will occupy a lot of "real estate" on the screen.
- You cannot input expressions for calculations as a formula, for example: 123.32-12.4/sin(1/2)
Every number, operator, or function must be entered separately, independent of one another.
Therefore you cannot edit expressions that were previously entered. For example you cannot calculate: 123.32-12.4/sin (1/2) and later 123.32-12.2/sin (1/2) You must enter all of the formula anew because one number is different then the other.
- Painted buttons provoke heavy mouse usage for input, but it will greatly reduce input speed of expressions. This is good for calculating, but it does promote fatigue of hand, due to mouse usage. For the necessary button search, a need is to permanently reread button captions or remember the last button location.
The LibMaster.com Extendable Calculator is a different way to approach calculator design. Therefore it does not contain any of the design defects, as outlined above.

MadCalc is a full featured graphing calculator application for your PC running Windows. With MadCalc you can graph rectangular, parametric, and polar equations. Plot multiple equations at once. Change the colors of graphs and the background. Use the immediate window feature to evaluate complex multivariate expressions. Teachers can use MadCalc to create handouts for your classroom. Students can use it instead of that tiny calculator screen while you are doing your calculus homework. MadCalc supports all the commonly used functions including trigonometric functions, inverse trigonometric functions, hyperbolic functions, logarithms, and rounding and absolute value functions. MadCalc allows you to export your work as bitmap files for printing or editing. MadCalc allows you to zoom in and out on graphs or set the scale in terms of x and y explicitly or scroll just by clicking on the graph and dragging it. MadCalc provides all the essential graphing functionality without the complexity, cost, or overhead of something like Mathematica or MatLab.
