double in hexadecimal notation, starting with 0x or 0X. a uses lower-case letters, A uses upper-case letters. [20] [21] (C++11 iostreams have a hexfloat that works the same). n: Print nothing, but writes the number of characters written so far into an integer pointer parameter. In Java this prints a newline. [22]
They have the form \uhhhh or \Uhhhhhhhh, where h stands for a hex digit. Unlike other escape sequences, a universal character name may expand into more than one code unit. The sequence \uhhhh denotes the code point hhhh, interpreted as a hexadecimal number. The sequence \Uhhhhhhhh denotes the code point hhhhhhhh, interpreted as a hexadecimal ...
%a : Scan a floating-point number in its hexadecimal notation. %d : Scan an integer as a signed decimal number. %i : Scan an integer as a signed number. Similar to %d, but interprets the number as hexadecimal when preceded by 0x and octal when preceded by 0. For example, the string 031 would be read as 31 using %d, and 25 using %i.
In computer science, an integer literal is a kind of literal for an integer whose value is directly represented in source code.For example, in the assignment statement x = 1, the string 1 is an integer literal indicating the value 1, while in the statement x = 0x10 the string 0x10 is an integer literal indicating the value 16, which is represented by 10 in hexadecimal (indicated by the 0x prefix).
Hexadecimal (also known as base-16 or simply hex) is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9 and "A"–"F" to represent values from ten to fifteen.

Format is a function in Common Lisp that can produce formatted text using a format string similar to the print format string.It provides more functionality than print, allowing the user to output numbers in various formats (including, for instance: hex, binary, octal, roman numerals, and English), apply certain format specifiers only under certain conditions, iterate over data structures ...
The number after the \u is a hexadecimal number; it does not need the usual 0x prefix. The identifier \u represents a 16-bit Unicode code point; to enter a 32-bit code point, use \U and a 32-bit hexadecimal number. Only valid Unicode code points can be entered.
