A simple calculator application
Hello,from this post i promised to write a simple class to ease the burden on my lovely calculator and bring my mechanics issues online,and so i did.I have now completed the class and here it is.
Calculator Library.Place it in your libraries folder:

class Calculator
{
function add( $num1, $num2)
{
return $num1 + $num2;
}
function subtract( $num1, $num2)
{
return $num1 - $num2;
}
function multiply( $num1, $num2)
{
return $num1 * $num2;
}
function divide( $num1, $num2)
{
return $num1 / $num2;
}
function getSine($value)
{
return sin($value);
}
function getCosine($value)
{
return cos($value);
}
function getTan($value)
{
return tan($value);
}
function getLogarithm($value)
{
return log($value);
}
function getPower($value1, $value2)
{
return pow($value1, $value2);
}
function getSqrt($value)
{
return sqrt($value);
}
function getFmod($value1, $value2)
{
return fmod($value1, $value2);
}
}
?>
Now here is the controller.Place it in your controllers folder.

class Calculate extends Controller
{
function calc()
{
$this->load->library('Calculator');
$a = 20;
$b = 4;
echo("The two numbers are $a and $b
\n");
$calca = new Calculator();
$sum = $calca->add($a, $b);
$sine = $calca->getSine($a);
echo ("The sine of $a is equal to $sine
\n");
echo("Their sum is $sum
\n");
}
}
?>
