Usage

Here is some examples about how to calculate two numbers.

Add two numbers

use Lee\Calculator\Calculator;
use Lee\Calculator\modules\GmpCalculator;
use Lee\Calculator\modules\BcMathCalculator;

$gmpCalculator = new Calculator(new GmpCalculator());
$bcMathCalculator = new Calculator(new BcMathCalculator());

echo $gmpCalculator->add('123456789', '123456789000000'); // 123456912456789
echo $bcMathCalculator->add('123456789', '123456789000000'); // 123456912456789

Minus two numbers

use Lee\Calculator\Calculator;
use Lee\Calculator\modules\GmpCalculator;
use Lee\Calculator\modules\BcMathCalculator;

$gmpCalculator = new Calculator(new GmpCalculator());
$bcMathCalculator = new Calculator(new BcMathCalculator());

echo $gmpCalculator->minus('123456789', '123456789000000'); // -123456665543211
echo $bcMathCalculator->minus('123456789', '123456789000000'); // -123456665543211

Multiple two numbers

use Lee\Calculator\Calculator;
use Lee\Calculator\modules\GmpCalculator;
use Lee\Calculator\modules\BcMathCalculator;

$gmpCalculator = new Calculator(new GmpCalculator());
$bcMathCalculator = new Calculator(new BcMathCalculator());

echo $gmpCalculator->mul('123456789', '123456789000000'); // 15241578750190521000000
echo $bcMathCalculator->mul('123456789', '123456789000000'); // 15241578750190521000000

Divide two numbers

use Lee\Calculator\Calculator;
use Lee\Calculator\modules\GmpCalculator;
use Lee\Calculator\modules\BcMathCalculator;

$gmpCalculator = new Calculator(new GmpCalculator());
$bcMathCalculator = new Calculator(new BcMathCalculator());

echo $gmpCalculator->divide('123456789000000', '123456789'); // 1000000
echo $bcMathCalculator->divide('123456789000000', '123456789'); // 1000000
