using printf with this ref

 

Where the specifier character at the end is the most significant component, since it defines the type and the interpretation of its corresponding argument:

specifier Output Example
d or i Signed decimal integer 392
u Unsigned decimal integer 7235
o Unsigned octal 610
x Unsigned hexadecimal integer 7fa
X Unsigned hexadecimal integer (uppercase) 7FA
f Decimal floating point, lowercase 392.65
F Decimal floating point, uppercase 392.65
e Scientific notation (mantissa/exponent), lowercase 3.9265e+2
E Scientific notation (mantissa/exponent), uppercase 3.9265E+2
g Use the shortest representation: %e or %f 392.65
G Use the shortest representation: %E or %F 392.65
a Hexadecimal floating point, lowercase -0xc.90fep-2
A Hexadecimal floating point, uppercase -0XC.90FEP-2
c Character a
s String of characters sample
p Pointer address b8000000
n Nothing printed.
The corresponding argument must be a pointer to a signed int.
The number of characters written so far is stored in the pointed location.
 
% A % followed by another % character will write a single % to the stream. %
