Rust 1.26.0 and up The :x? “debug with hexadecimal integers” formatter can be used: let data = b”hello”; // lower case println!(“{:x?}”, data); // upper case println!(“{:X?}”, data); let data = [0x0, 0x1, 0xe, 0xf, 0xff]; // print the leading zero println!(“{:02X?}”, data); // It can be combined with the pretty modifier as well println!(“{:#04X?}”, … Read more
The Numeric module includes several functions for showing an Integral type at various bases, including showIntAtBase. Here are some examples of use: import Numeric (showHex, showIntAtBase) import Data.Char (intToDigit) putStrLn $ showHex 12 “” — prints “c” putStrLn $ showIntAtBase 2 intToDigit 12 “” — prints “1100”
For people that end up here and are just looking for the hex representation of a (binary) string. bin2hex(“that’s all you need”); # 74686174277320616c6c20796f75206e656564 hex2bin(‘74686174277320616c6c20796f75206e656564’); # that’s all you need Doc: bin2hex, hex2bin.
printf ‘\x31\xc0\xc3′ | dd of=test_blob bs=1 seek=100 count=3 conv=notrunc dd arguments: of | file to patch bs | 1 byte at a time please seek | go to position 100 (decimal) conv=notrunc | don’t truncate the output after the edit (which dd does by default) One Josh looking out for another 😉
Hex values are easier to copy and paste from your favourite image editor. RGB values are easier to manipulate with Javascript. (My favourite Hex colour value is #EDEDED and a site we made for a client involved in motorsport had a background colour of #F1F1F1 🙂 Ed.
CSS 2.1 (http://www.w3.org/TR/CSS2/syndata.html#value-def-color): The three-digit RGB notation (#rgb) is converted into six-digit form (#rrggbb) by replicating digits, not by adding zeros. For example, #fb0 expands to #ffbb00. This ensures that white (#ffffff) can be specified with the short notation (#fff) and removes any dependencies on the color depth of the display. Wordings of CSS 1, … Read more
You can still use the Java conversion by calling the static function on java.lang.Integer: val hexString = java.lang.Integer.toHexString(i) And, starting with Kotlin 1.1, there is a function in the Kotlin standard library that does the conversion, too: fun Int.toString(radix: Int): String Returns a string representation of this Int value in the specified radix. Note, however, … Read more
Check example link below and click on the div to get the color value in hex. var color=””; $(‘div’).click(function() { var x = $(this).css(‘backgroundColor’); hexc(x); console.log(color); }) function hexc(colorval) { var parts = colorval.match(/^rgb\((\d+),\s*(\d+),\s*(\d+)\)$/); delete(parts[0]); for (var i = 1; i <= 3; ++i) { parts[i] = parseInt(parts[i]).toString(16); if (parts[i].length == 1) parts[i] = ‘0’ … Read more
int given base 2 and then hex: >>> int(‘010110’, 2) 22 >>> hex(int(‘010110’, 2)) ‘0x16’ >>> >>> hex(int(‘0000010010001101’, 2)) ‘0x48d’ The doc of int: int(x[, base]) -> integer Convert a string or number to an integer, if possible. A floating point argument will be truncated towards zero (this does not include a string representation of … Read more
echo bin2hex($string); or: for ($i = 0; $i < strlen($string); $i++) { echo str_pad(dechex(ord($string[$i])), 2, ‘0’, STR_PAD_LEFT); } $string is the variable which contains input.
