note 109169 added to function.hexdec

When given large numbers, the hexdec function automatically converts the value to scientific notation. So, "aa1233123124121241" as a hexadecimal value will be converted to "3.13725790445E+21". If you're converting a hexadecimal value that represents a hash value (md5 or sha), then you need every single bit of that representation to make it useful. By using the number_format function, you can do that perfectly. For example : <?php // Author: holdoffhunger@gmail.com // Example Hexadecimal // --------------------------------------------- $hexadecimal_string = "1234567890abcdef1234567890abcdef"; // Converted to Decimal // --------------------------------------------- $decimal_result = hexdec($hexadecimal_string); // Print Pre-Formatted Results // --------------------------------------------- print($decimal_result); // Output Here: "2.41978572002E+37" // ..................................... // Format Results to View Whole All Digits in Integer // --------------------------------------------- // ( Note: All fractional value of the // Hexadecimal variable are ignored // in the conversion. ) $current_hashing_algorithm_decimal_result = number_format($decimal_result, 0, '', ''); // Print Formatted Results // --------------------------------------------- print($current_hashing_algorithm_decimal_result); // Output Here: "24197857200151253041252346215207534592" // ..................................... ?> ---- Server IP: 69.147.83.197 Probable Submitter: 68.9.137.178 ---- Manual Page -- http://www.php.net/manual/en/function.hexdec.php Edit -- https://master.php.net/note/edit/109169 Del: integrated -- https://master.php.net/note/delete/109169/integrated Del: useless -- https://master.php.net/note/delete/109169/useless Del: bad code -- https://master.php.net/note/delete/109169/bad+code Del: spam -- https://master.php.net/note/delete/109169/spam Del: non-english -- https://master.php.net/note/delete/109169/non-english Del: in docs -- https://master.php.net/note/delete/109169/in+docs Del: other reasons-- https://master.php.net/note/delete/109169 Reject -- https://master.php.net/note/reject/109169 Search -- https://master.php.net/manage/user-notes.php
