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. 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 (
