Section XCU 2.14 / printf
Page Number 3086
Line Number 104321
Final Accepted Text Note: 0005390
Summary 0001476: Missing '+' character in the second example explanation
Description printf(1) contains an example

    printf "%d\n" 3 +3 -3 \'3 \"+3 "'-3"

which for the first two lines output, is stated to produce

    3 Numeric value of constant 3
    3 Numeric value of constant 3

The second of those should be

    3 Numeric value of constant +3

to match the command line given.
Desired Action In line 104321 on page 3086 (XCU 2.14, printf, EXAMPLES)
(in issue 8, draft 2) change:

Numeric value of constant 3


to:

Numeric value of constant +3



As an optional extra (not a bug) it might be worth adding one more
constant to the command line (or two) and showing the output from
it (or them) as well, where the added command line arg(s) would be
hex &/or octal representations (0x1C or 0254 or whatever you like).

 Suggested changes...

After line 104302 on page 3085 (XCU 2.14, printf, EXAMPLES), add:
The command:
printf '%d\n' 10 010 0x10
produces:
10
8
16

If the implementation supports floating-point conversions, the command:
printf '%.2f\n' 10 010 0x10 10.1e2 010.1e2 0x10.1p2
produces:
10.00
10.00
16.00
1010.00
1010.00
64.25

In line 104321 on page 3086 (XCU 2.14, printf, EXAMPLES), change:
Numeric value of constant 3
to:
Numeric value of constant +3

 After line 104302 on page 3085 (XCU 2.14, printf, EXAMPLES), add:
The command:
printf '%d\n' 10 010 0x10
produces:
<table>
<tr><th>Output Line</th><th>Explanation</th></tr>
<tr><td><tt>10</tt></td><td>Decimal representation of the numeric value of decimal integer constant 10</td></tr>
<tr><td><tt>8</tt></td><td>Decimal representation of the numeric value of octal integer constant 010</td></tr>
<tr><td><tt>16</tt></td><td>Decimal representation of the numeric value of hexadecimal integer constant 0x10</td></tr>
</table>

If the implementation supports floating-point conversions, the command:
LC_ALL=C printf '%.2f\n' 10 010 0x10 10.1e2 010.1e2 0x10.1p2
produces:
<table>
<tr><th>Output Line</th><th>Explanation</th></tr>
<tr><td><tt>10.00</tt></td><td>The string "10" interpreted as a decimal value, with 2 digits of precision.</td></tr>
<tr><td><tt>10.00</tt></td><td>The string "010" interpreted as a decimal (not octal) value, with 2 digits of precision.</td></tr>
<tr><td><tt>16.00</tt></td><td>The string "0x10" interpreted as a hexadecimal value, with 2 digits of precision.</td></tr>
<tr><td><tt>1010.00</tt></td><td>The string "10.1e2" interpreted as a decimal floating-point value, with 2 digits of precision.</td></tr>
<tr><td><tt>1010.00</tt></td><td>The string "010.1e2" interpreted as a decimal (not octal) floating-point value, with 2 digits of precision.</td></tr>
<tr><td><tt>64.25</tt></td><td>The string "0x10.1p2" interpreted as a hexadecimal floating-point value, with 2 digits of precision.</td></tr>
</table>

On page 3086 replace lines 104317-104325 with:
In a locale that uses a codeset based on ISO/IEC 646: 1991, the command:
printf "%d\n" 3 +3 -3 \'3 \"+3 "'-3"
produces:
<table>
<tr><th>Output Line</th><th>Explanation</th></tr>
<tr><td><tt>3</tt></td><td>Decimal representation of the numeric value 3</td></tr>
<tr><td><tt>3</tt></td><td>Decimal representation of the numeric value +3</td></tr>
<tr><td><tt>-3</tt></td><td>Decimal representation of the numeric value -3</td></tr>
<tr><td><tt>51</tt></td><td>Decimal representation of the numeric value of the character <tt>'3'</tt> in the ISO/IEC 646: 1991 standard codeset</td></tr>
<tr><td><tt>43</tt></td><td>Decimal representation of the numeric value of the character <tt>'+'</tt> in the ISO/IEC 646: 1991 standard codeset</td></tr>
<tr><td><tt>45</tt></td><td>Decimal representation of the numeric value of the character <tt>'-'</tt> in the ISO/IEC 646: 1991 standard codeset</td></tr>
</table>

In the paragraph at line 104326, move the second sentence ("Since the last two ...") to before the first sentence ("Note that in a locale ...").
