How do I convert hex to decimal in Python? [duplicate]
If by “hex data” you mean a string of the form s = “6a48f82d8e828ce82b82” you can use i = int(s, 16) to convert it to an integer and str(i) to convert it to a decimal string.

To convert from decimal to hex do… string hexValue = decValue.ToString(“X”); To convert from hex to decimal do either… int decValue = int.Parse(hexValue, System.Globalization.NumberStyles.HexNumber); or int decValue = Convert.ToInt32(hexValue, 16);
You can transform your string to an integer generator. Apply hexadecimal formatting for each element and intercalate with a separator: >>> s = “Hello, World!” >>> “:”.join(“{:02x}”.format(ord(c)) for c in s) ’48:65:6c:6c:6f:2c:20:57:6f:72:6c:64:21
Use: #include <iostream> … std::cout << std::hex << a; There are many other options to control the exact formatting of the output number, such as leading zeros and upper/lower case.
To view the file, run: xxd filename | less To use Vim as a hex editor: Open the file in Vim. Run :%!xxd (transform buffer to hex) Edit. Run :%!xxd -r (reverse transformation) Save.
A slightly simpler solution: >>> “7061756c”.decode(“hex”) ‘paul’
Use <iomanip>‘s std::hex. If you print, just send it to std::cout, if not, then use std::stringstream std::stringstream stream; stream << std::hex << your_int; std::string result( stream.str() ); You can prepend the first << with << “0x” or whatever you like if you wish. Other manips of interest are std::oct (octal) and std::dec (back to decimal). … Read more
Here is the table of % to hex values: Example: For 85% white, you would use #D9FFFFFF. Here 85% = “D9” & White = “FFFFFF” 100% — FF 95% — F2 90% — E6 85% — D9 80% — CC 75% — BF 70% — B3 65% — A6 60% — 99 55% — 8C … Read more
TLDR Use this clean one-line function with both rgb and rgba support: const rgba2hex = (rgba) => `#${rgba.match(/^rgba?\((\d+),\s*(\d+),\s*(\d+)(?:,\s*(\d+\.{0,1}\d*))?\)$/).slice(1).map((n, i) => (i === 3 ? Math.round(parseFloat(n) * 255) : parseFloat(n)).toString(16).padStart(2, ‘0’).replace(‘NaN’, ”)).join(”)}` 2021 updated answer Much time has passed since I originally answered this question. Then cool ECMAScript 5 and 2015+ features become largely available on … Read more
Here’s an adaptation of CD Sanchez’ answer that consistently returns a 6-digit colour code: var stringToColour = function(str) { var hash = 0; for (var i = 0; i < str.length; i++) { hash = str.charCodeAt(i) + ((hash << 5) – hash); } var colour=”#”; for (var i = 0; i < 3; i++) { … Read more
