fprintf

to be formatted and printed 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 printed 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

precision

to be expanded, and the octal value is printed with a

leading zero (a C convention). The

precision

parameter 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

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

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

precision

is not 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.

e The float or double

item

is converted to scientiﬁc notation in style e;

that is, in the form
