Interprets EXPR as a hex string and returns the corresponding value. (To convert strings that might start with either
0x , or
0b, see oct.) If EXPR is omitted, uses
print hex '0xAf'; # prints '175' 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.
