The optional fields, which appear before the type character, control other
aspects of the formatting, as follows:
„
type
Required character that determines whether the associated argument is inter-
preted as a character, a string, or a number.
„
flags
Optional character or characters that control justification of output and printing
of signs, blanks, decimal points, and octal and hexadecimal prefixes. More than
one flag can appear in a format specification.
Character Type Output Format
c or C int or char Specifies a single-byte character.
d int Signed decimal integer.
i int Signed decimal integer.
o . int Unsigned octal integer
u int Unsigned decimal integer.
x int Unsigned hexadecimal integer, using “abcdef.”
X int Unsigned hexadecimal integer, using “ABCDEF.”
e double Signed value having the form [ - ]d.dddd e
[sign]ddd where d is a single decimal digit, dddd is
one or more decimal digits, ddd is exactly three
decimal digits, and sign is + or -.
E double Identical to the e format except that E rather than e
introduces the exponent.
f double Signed value having the form [ - ]dddd.dddd,
where dddd is one or more decimal digits. The
number of digits before the decimal point depends
on the magnitude of the number, and the number
of digits after the decimal point depends on the
requested precision.
g double Signed value printed in f or e format, whichever is
more compact for the given value and precision.
The e format is used only when the exponent of
the value is less than -4 or greater than or equal to
the precision argument. Trailing zeros are trun-
cated, and the decimal point appears only if one or
more digits follow it.
G double Identical to the g format, except that E, rather than
e, introduces the exponent (where appropriate).
s or S String Specifies a single-byte - character string. Charac-
ters are printed up to the first null character or until
the precision value is reached.
Flag Meaning Default
- Left align the result within the given field width. Right align.
+ Prefix the output value with a sign (+ or -) if the
output value is of a signed type Sign appears only
for negative
signed values (-).
0 If width is prefixed with 0, zeros are added until the
minimum width is reached. If 0 and ®C appear,
the 0 is ignored. If 0 is specified with an integer
format (i, u, x, X, o, d) the 0 is ignored. No padding.
