Math - Calculators (20)

QwikTape is a calculator that allows you to create unlimited documents called tapes and switch between them easily using browser-like tabs.

Additional features:

• Write text, calculate, annotate it like you would on a paper or in a book.
• Never forget what was the calculation about by annotating it.
• Do calculations like addition +, subtraction -, division ÷, multiplication ×, percentage % and power ^.
• Create unlimited tapes using [+] button in tabs bar, switch between tapes using tabs.
• View/Rename/Delete your saved tapes in the Bookmark menu, use the top left menu to view all tapes.
• Tapes are auto saved.
• The numbers will auto format and auto indented as you type.
• Numbers are formatted according to the locale.
• User can define variables and use it in calculations.
• Hover cursor over variables to check it's value.
• Customize colors using the settings menu, number of decimals to use and indent length can be changed too.
• Tape calculation doesn't use operator precedence, the results will be as you would type it on a calculator.
• Expressions use operator precedence.
• All the calculations are done with infinite precision.
• Offers builds for MacOS and Linux also.

Kalkules is an universal scientific calculator that comes with many nontraditional functions and built-in tools designed to make your calculations easier and faster.

ESBCalc is a scientific calculator with Infix Notation, Brackets, Scientific Functions (Trigonometric, Hyperbolic, Logarithmic - including Base 10, Base 2 & Natural - plus more), Memory, Paper Trail, Result History List and more. As of version 5, support for Prefix functions is included so to evaluate log (10) you can enter log 10 rather than 10 log (which is the default behavior).

DateDiff is a calendar program that allows you to select two different dates, then calculates the number of days, hours, minutes and seconds between them. It can also determines what the date is X number of days before or after a given date.

Note: DateDiff 3.0 is not portable. We are linking to the a mirror of the last fully portable version (thanks to user Snidley).

XCALC is a highly configurable calculator that can be used for simple calculations using decimal or complex floating point, or hexadecimal, octal or binary integer numbers. The program uses RPN (Reverse Polish Notation), similar to the classic Hewlett Packard handhelds. You can choose from anything between a small window consisting of a single number display only (which you can float above other programs) to a full-fledged big display with all colors, buttons, bells and whistles.

SpeedCrunch is a high-precision scientific calculator featuring a fast, keyboard-driven user interface.

Feature list:

• Displays results as you type. Select a partial expression to evaluate only that part.
• Previous inputs and results are shown in a scrollable history and can be easily recalled. Customizable syntax highlighting allows you to spot mistakes easily.
• If you prefer the old-school way, an optional on-screen keypad is available as well.
• Comes with over 80 built-in mathematical functions. You can also define your own functions.
• Variables allow you to store your results. Perform calculations with up to 50 digits of precision, using complex numbers, numeral bases, unit conversions, and more.
• Auto-completion allows you to speed up your task.
• A built-in formula book allows you to review and insert commonly used formulas, such as the volume of a cone.
• Over 150 built-in scientific constants available.

CalcPad is a unique way to combine natural language with standard math calculations. The program supports allows you to enter expressions, assign variables, define functions, convert units, add units together and much more. The program automatically evaluates everything you type as entered. Just like a notepad, you can go back and edit, add, or delete as needed.

Euler Math Toolbox is a numerical and symbolic math toolbox. Symbolic computation are done by working with Euler's native capabilities and also in conjunction with a seamlessly integrated version of Maxima computer algebra system. Euler Math Toolbox can also be used with LaTeX and Python (integration instructions). Euler Math Toolbox also supports the capabilities of using the built in C compiler (Tiny C) to run C code for important mathematical routines where high performances are required.

The program is developed by a math professor (Rene Grothmann) at the University of Eichstätt in Germany. Examples of problems solved with this program.

Day Maxi Calc is a super-sized calculator, with a large button set and wide display. It has all the basic functions and also simulates the classic roll of paper. There is also the option of printing and/or saving your results.
