  • hex EXPR

  • hex

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

    1.  print hex '0xAf'; # prints '175'
      2.  
    2.  print hex 'aF';   # same
      3.

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