Conversion Characters
Conversion characters specify the type of data to expect in the item list and cause the data
to be formatted and written appropriately. The integer conversion characters are:
d, i An integer
item is converted to signed decimal. The precision , if given,
specifies the minimum number of digits to appear. If the value has fewer
digits than that specified by the
precision , the value is expanded with
leading zeros. The default
precision is 1. A null string results if a zero
value is written with a zero
precision . The # flag has no effect.
u An integer
item is converted to unsigned decimal. The effects of the
precision and the # flag are the same as for d.
o An integer
item is converted to unsigned octal. The # flag, if specified,
causes the
precision to be expanded, and the octal value is written with a
leading zero (a C convention). The
precision behaves the same as in d
above, except that writing a zero value with a zero
precision results in
only the leading zero being written, if the # flag is specified.
x An integer
item is converted to hexadecimal. The letters abcdef are used
in writing hexadecimal values. The # flag, if specified, causes the
precision to be expanded, and the hexadecimal value is written with a
leading "0x" (a C convention). The
precision behaves as in d above,
except that writing a zero value with a zero
precision results in only the
leading "0x" being written, if the # flag is specified.
X Same as x above, except that the letters ABCDEF are used to write the
hexadecimal value, and the # flag causes the value to be written with a
leading "0X".
The character conversion characters are as follows:
c The character specified by the char
item is written. The precision is
meaningless, and the # flag has no effect.
s The string pointed to by the character pointer
item is written. If a
precision is specified, characters from the string are written until the
number of characters indicated by the
precision is reached, or until a
null character is encountered, whichever comes first. If the
precision is
omitted, all characters up to the first null character are written. The # flag
has no effect.
The floating-point conversion characters are:
f The float or double
item is converted to decimal notation in style f; that
is, in the form
[-]ddd.ddd
where the number of digits after the decimal point is equal to the
precision . If no precision is specified, six digits are written after the
decimal point. If the
precision is explicitly zero, the decimal point is
eliminated entirely. If the # flag is specified, a decimal point always
appears, even if no digits follow the decimal point.
