First, create a file and name it "calculator.html" and then type the following command:
<html> <head> <title>Simple Calculator Online</title> </head> <body> <form name="form1" method="post" action="count.php"> <p>Mathematical Operators</p> <p> <input name="angka" type="text" id="angka"> <select name="operator" id="operator"> <option>+</option> <option>-</option> <option>*</option> <option>/</option> </select> <input name="angka2" type="text" id="angka2"> <input type="submit" name="Submit" value="Calculate"> </p> </form> <form name="form2" method="post" action="count2.php"> <p>Mathematical Constants</p> <p> <input name="angka" type="text" id="angka"> <select name="operator" id="operator"> <option>abs</option> <option>floor</option> <option>round</option> <option>decbin</option> <option>bindec</option> <option>decoct</option> <option>octdec</option> <option>dechex</option> <option>hexdec</option> <option>sin</option> <option>cos</option> <option>tan</option> <option>log</option> <option>sqrt</option> </select> <input type="submit" name="Submit" value="Hitung"> </p> <p>Keterangan :</p> <table width="100%" border="0"> <tr> <td>+</td> <td>=</td> <td>Plus.</td> </tr> <tr> <td>-</td> <td>=</td> <td>Minus.</td> </tr> <tr> <td>*</td> <td>=</td> <td>Multiple.</td> </tr> <tr> <td>/</td> <td>=</td> <td>Divide.</td> </tr> <tr> <td width="4%">abs</td> <td width="2%">=</td> <td width="94%">Returns the absolute value of number .</td> </tr> <tr> <td>floor</td> <td>=</td> <td>Returns the next lowest integer value by rounding down value if necessary. </td> </tr> <tr> <td>round</td> <td>=</td> <td>Returns the rounded value of val to specified precision (number of digits after the decimal point). </td> </tr> <tr> <td>decbin</td> <td>=</td> <td>Convert an integer to binary number. </td> </tr> <tr> <td>bindec</td> <td>=</td> <td>Convert a binary number to an integer. (opposite of decbin) </td> </tr> <tr> <td>decoct</td> <td>=</td> <td>Convert an integer to an octal. </td> </tr> <tr> <td>octdec</td> <td>=</td> <td>Convert an octal to an integer (opposite of decoct) </td> </tr> <tr> <td>dechex</td> <td>=</td> <td>Convert an integer to a Hexadesimal. </td> </tr> <tr> <td>hexdec</td> <td>=</td> <td>Convert a Hexadecimal to an integer (opposite of dechex). </td> </tr> <tr> <td>sin</td> <td>=</td> <td>sine</td> </tr> <tr> <td>cos</td> <td>=</td> <td>cosine</td> </tr> <tr> <td>tan</td> <td>=</td> <td>tangent</td> </tr> <tr> <td>log</td> <td>=</td> <td>log</td> </tr> <tr> <td>sqrt</td> <td>=</td> <td>Returns the square root of arg</td> </tr> </table> </form> <p> </p> </body> </html> |
Then for the second, create a file with the name "count.php" and type the following script :
<?php $number = $_POST['number']; $number2 = $_POST['number2']; $operator = $_POST['operator']; if ($operator == '+') { $output = $number+$number2; } if ($operator == '-') { $output = $number-$number2; } if ($operator == '*') { $output = $number*$number2; } if ($operator == '/') { $output = $number/$number2; } print "$output"; ?> |
And for the last, create a file with the name "count2.php" and then type the following script:
<?php $number = $_POST['number']; $operator = $_POST['operator']; if ($operator == 'abs') { $output = abs($number); } if ($operator == 'floor') { $output = floor($number); } if ($operator == 'round') { $output = round($number); } if ($operator == 'decbin') { $output = decbin($number); } if ($operator == 'bindec') { $output = bindec($number); } if ($operator == 'decoct') { $output = octdec($number); } if ($operator == 'octdec') { $output = octdec($number); } if ($operator == 'dechex') { $output = dechex($number); } if ($operator == 'hexdec') { $output = hexdec($number); } if ($operator == 'sin') { $output = sin($number); } if ($operator == 'cos') { $output = cos($number); } if ($operator == 'tan') { $output = tan($number); } if ($operator == 'log') { $output = log($number); } if ($operator == 'sqrt') { $output = sqrt($number); } print "$output"; ?> |
That's all....you may try it...
