## What is Command?

Command-Line Calculator (CLCalculator) provides the most fluid interface, especially if you are performing chained calculations i.e. multiple calculations that rely on the results of previous calculations.

By providing a command-line interface, CLCalculator allows you to easily enter and view the history of your calculations. You focus on your calculations instead of being intimidated by myriad of buttons on a traditional calculator interface! In addition to performing basic calculations, CLCalculator provides an array of features such as:

- Assign and reuse variables
- Complex numbers
- Number bases i.e. binary, octal, hexadecimal
- Constants e.g. e, pi
- String manipulation
- Matrices
- Unit conversion: in-built and user-defined  (create your own units!)
- Functions: in-built and user-defined (create your own functions!)
- Arithmetic functions e.g. fraction, square root, rounding off, ceiling, floor, logarithm
- Algebra functions e.g. derivative, simplify symbolic expressions, solve linear equations
- Bitwise functions e.g. bitwise and, not, or, left and right shift
- Combinatorics functions e.g. Bell, Catalan, Stirling numbers 
- Geometry functions
- Logical functions e.g. and, not, or, xor
- Probability functions e.g. combinations, permutations, factorial
- Relational functions
- Set functions e.g. cartesian product, intersection, union
- Statistics functions e.g. mean, median, mode, standard deviation, variance
- Trigonometry functions e.g. sin, cos, tan, cot, sinh, acos
- and much more!

The app also comes with a comprehensive in-built help system with plenty of examples. CLCalculator is powered by math.js (https://mathjs.org/)

### 5/5 — Wonderful !

*2026-02-05*

I tried a couple of others, but I can honestly say I like this one the best. It’s very intuitive, I think its power lies within the command line interface, you can cursor up to repeat something after you’ve modified the answer. So it’s quick. Just hitting ( +, - , *, / ) after a calc, and it substitutes the prior answer first. Smart !

### 5/5 — Great App

*2024-09-11*

It’s like a little iOS version of Numbat or MATLAB! The unit support is my favorite feature, however. Incredibly useful for double-checking hand calculations for engineering courses.

### 4/5 — Great and straight forward text based calculator

*2022-10-18*

Thanks for taking the time to make this. Would love to see an option for comma seperated values in a future release (however, if commas are used, the raw non-comma seperated value would be copied to the clipboard for use in another application.)

**Developer response:** Thank you for your review! We understand that displaying comma-separated values may be useful in some cases. However, the app has many functionalities where commas in numbers will lead to misinterpretations. For example, an array containing 1100 and 2400 is currently displayed as [1100,2400]. With comma-separated values, it would be displayed as  [1,100,2,400], which may be misinterpreted as an array of 4 numbers.
