  • hex

    Interprets EXPR as a hex string and returns the corresponding value. (To convert strings that might start with either 0 , 0x , or 0b, see oct.) If EXPR is omitted, uses $_ .

    1.     print hex '0xAf'; # prints '175'
    2.     print hex 'aF';   # same

    Hex strings may only represent integers. Strings that would cause integer overflow trigger a warning. Leading whitespace is not stripped, unlike oct(). To present something as hex, look into printf, sprintf, and unpack.
