Simple to use modular calculator with steps to solution and result explanation.
It is highly recommended to make sure you have enabled BCMath or GMP extension on your PHP server for much faster calculations.
composer require mathematicator-core/calculator
Imagine you want compute some math problem, for instance:
(5 + 3) * (2 / (7 + 3))
How to compute it? Very simply:
$calculator = new Calculator(/* some dependencies */);
echo $calculator->calculateString('(5 + 3) * (2 / (7 + 3))'); // \frac{8}{5}Method calculateString() returns entity CalculatorResult that implements __toString() method.
Advance use is by an array of tokens created by Tokenizer:
$tokenizer = new Tokenizer(/* some dependencies */);
// Convert math formule to array of tokens:
$tokens = $tokenizer->tokenize('(5+3)*(2/(7+3))');
// Now you can convert tokens to more useful format:
$objectTokens = $tokenizer->tokensToObject($tokens);
$calculator->calculate($objectTokens);The biggest advantage is that you can choose which layer best fits your needs and start build on the top of it, immediately, without the need to create everything by yourself. Our tools are tested for bugs and tuned for performance, so you can save a significant amount of your time, money, and effort.
Framework tend to be modular as much as possible, so you should be able to create an extension on each layer and its sublayers.
Mathematicator framework layers ordered from the most concrete one to the most abstract one:
| Search | Modular search engine layer that calls its sublayers and creates user interface. |
| Vizualizator |
Elegant graphic visualizer that can render to
SVG, PNG, JPG and Base64. Extensions: Mandelbrot set generator |
| Calculator |
Modular advance calculations layer.
Extensions: Integral Solver , Statistics |
| Engine | Core logic layer that maintains basic controllers, DAOs, translator, common exceptions, routing etc. |
| Tokenizer | Tokenizer that can convert string (user input / LaTeX) to numbers and operators. |
| Numbers | Fast & secure storage for numbers with arbitrary precision. It supports Human string and LaTeX output and basic conversions. |
Third-party packages:
| REST API | Install the whole pack as a REST API service on your server (Docker ready) or access it via public cloud REST API. |
