The class providing you to use complex numbers.
This class support many main things to work with imaginary numbers, for example
- add real and complex number
- add complex with complex number
- multiply real and complex number
- multiply complex and complex number
- divide complex by real
- divide complex by complex
- divide real by complex
- power complex number by real exponent (negative and fraction too)
- get integer root of complex number
- get argument of complex number
- get module (absolute) of complex number
Include the class file in your code. Than you need create as many numbers as you need. Complex numbers in the class have the form a+b*i, where a and b is real and i is imaginary unit. To create complex number use code like this:
...
$complexNumber1 = new complexNumber($a, $b);
...There are many methods to manipulate with created number, class structure:
class complexNumber {
public var $a, $b; // a and b from a+b*i
boolean public function __construct(numeric $a, numeric $b) { ... } // Initialize class
string public function getNumber() { ... } // Returns $a.'+'.$b.'*i'
complexNumber public function add(numeric/complexNumber $number) { ... } // Add $number to your complex number
complexNumber public function sub(numeric/complexNumber $number) { ... } // Subtract $number to your complex number
complexNumber public function multiply(numeric/complexNumber $number) { ... } // Multiply $number to your complex number
complexNumber public function divide(numeric/complexNumber $number) { ... } // Divide $number to your complex number
float public function absolute() { ... } // Get an absolute (module) of the complex number
float public function argument() { ... } // Get an argument of the complex number
complexNumber public function power(numeric $number) { ... } // Power your complex number by $exponent
complexNumber public function root(int $base, $k = 0 /* Number of root (there are $base of them) */) { ... } // Make $base`s root of complex number
