RedCrab - the scientific calculator with full screen formula editor.
High Precision Complex Calculator
This programmable calculator does real or complex number calculations with 100 significant figure precision. Many standard functions such as trig, hyperbolic, logarithms and base conversions are included. Loops are supported. Both expressions and results can be saved to a file.
This application can be used to easily calculate the resistor values needed to achieve a specified attenuation in a controlled impedance environment.
HEXelon MAX is a free mathematical calculator, currency converter, and units converter.
Multicalc was written specifically for calculating time, but it can also be used as a normal calculator and for converting decimal numbers to binary, binary to decimal, decimal to hexadecimal, and hexadecimal to decimal.
ShowCalc 3.01 (last freeware version).
32-bit calculator that, in addition to basic arithmetic, memory and scientific functions (hex, trig, and log modules), includes an extremely useful, scrolling 'tape Window' that allows you to easily view your work. You can then print this adding machine-like tape, or copy the data onto your clipboard for use in other applications.
Calcute is a Free, Compact yet Capable Calculator. Features: Process sequences of arbitrarily complex arithmetic expressions like:
-log(1+2) * 3% + sin(4 5/6)^7
Edit previous calculations and re-calculate, cut and paste at will. Save your work to a text file (automatic or manual), restore it later. Compact single-line mode or flexible multi-line mode. Show buttons or hide them. Separately adjustable font and button sizes. Flexible snap-on screen positioning to your preferred location. Enable/disable "always on top" style. Help file included.
Calculator Prompter is a math expression calculator. Calcualtor Prompter has a built-in error recognition system that helps you get correct results. With Calculator Prompter you can enter the whole expression, including brackets, and operators. You can use Calculator to perform any of the standard operations for which you would normally use a handheld calculator. Calculator performs arithmetic, such as root (#) and power (^).
TextCalc is a combination of an expression calculator and a text editor. Being both, it has several advantages over conventional calculators.
1) You can evaluate expressions like 9x4-2+95-12 just the way you write them on paper.
2) You can put comments besides your answer and expressions.
3) You can save and reuse your results and expressions.
4) You do not need to write your answer down on a paper before computing another expression, as you can leave the previous result in the editor.
5) You can open an existing text data file and perform calculations on it.
6) You can apply an expression to many numbers at one go. For example, you can change the list 1 2 3 4 5 to 2 4 6 8 10 by multiplying each number by 2.
7) You can sum, average, convert into hex etc. a list of numbers easily.
Currency calculator with tape - emulation of printing calculator. Easy and simple, can be operated entirely by keyboard. Supports COPY/PASTE, UNDO for last operation.
Excalibur for Windows 32-bit version is a freeware full featured RPN-only calculator. This is a serious calculator for serious users. Excalibur takes up a small amount of resources for all it does so well.
Excalibur does not use more conventional "algebraic" notation like many low-end calculators on the market. Instead it uses the high-powered parenthesis-free RPN notation (Reverse Polish Notation).
RPN is really nothing more than the method of entry of numbers and operators into the calculator.
