<h4 class="subsection">14.2.7 Table of Output Conversions</h4>
<a name="index-output-conversions_002c-for-printf"></a>
<p>Here is a table summarizing what all the different conversions do:
</p>
<dl compact="compact">
<dt>‘<samp>%d</samp>’, ‘<samp>%i</samp>’</dt>
<dd><p>Print an integer as a signed decimal number. See <a href="Integer-Conversions.html#Integer-Conversions">Integer Conversions</a>, for details. ‘<samp>%d</samp>’ and ‘<samp>%i</samp>’ are synonymous for
output, but are different when used with <code>scanf</code> for input
(see <a href="Table-of-Input-Conversions.html#Table-of-Input-Conversions">Table of Input Conversions</a>).
</p>
</dd>
<dt>‘<samp>%o</samp>’</dt>
<dd><p>Print an integer as an unsigned octal number. See <a href="Integer-Conversions.html#Integer-Conversions">Integer Conversions</a>, for details.
</p>
</dd>
<dt>‘<samp>%u</samp>’</dt>
<dd><p>Print an integer as an unsigned decimal number. See <a href="Integer-Conversions.html#Integer-Conversions">Integer Conversions</a>, for details.
</p>
</dd>
<dt>‘<samp>%x</samp>’, ‘<samp>%X</samp>’</dt>
<dd><p>Print an integer as an unsigned hexadecimal number. ‘<samp>%x</samp>’ uses
lowercase letters and ‘<samp>%X</samp>’ uses uppercase. See <a href="Integer-Conversions.html#Integer-Conversions">Integer Conversions</a>, for details.
</p>
</dd>
<dt>‘<samp>%f</samp>’</dt>
<dd><p>Print a floating-point number in normal (fixed-point) notation.
See <a href="Floating_002dPoint-Conversions.html#Floating_002dPoint-Conversions">Floating-Point Conversions</a>, for details.
</p>
</dd>
<dt>‘<samp>%e</samp>’, ‘<samp>%E</samp>’</dt>
<dd><p>Print a floating-point number in exponential notation. ‘<samp>%e</samp>’ uses
lowercase letters and ‘<samp>%E</samp>’ uses uppercase. See <a href="Floating_002dPoint-Conversions.html#Floating_002dPoint-Conversions">Floating-Point Conversions</a>, for details.
</p>
</dd>
<dt>‘<samp>%g</samp>’, ‘<samp>%G</samp>’</dt>
<dd><p>Print a floating-point number in either normal (fixed-point) or
exponential notation, whichever is more appropriate for its magnitude.
‘<samp>%g</samp>’ uses lowercase letters and ‘<samp>%G</samp>’ uses uppercase.
See <a href="Floating_002dPoint-Conversions.html#Floating_002dPoint-Conversions">Floating-Point Conversions</a>, for details.
</p>
</dd>
<dt>‘<samp>%c</samp>’</dt>
<dd><p>Print a single character. See <a href="Other-Output-Conversions.html#Other-Output-Conversions">Other Output Conversions</a>.
</p>
</dd>
<dt>‘<samp>%s</samp>’</dt>
<dd><p>Print a string. See <a href="Other-Output-Conversions.html#Other-Output-Conversions">Other Output Conversions</a>.
</p>
</dd>
<dt>‘<samp>%%</samp>’</dt>
<dd><p>Print a literal ‘<samp>%</samp>’ character. See <a href="Other-Output-Conversions.html#Other-Output-Conversions">Other Output Conversions</a>.
</p></dd>
</dl>
<p>If the syntax of a conversion specification is invalid, unpredictable
things will happen, so don’t do this. If there aren’t enough function
arguments provided to supply values for all the conversion
specifications in the template string, or if the arguments are not of
the correct types, the results are unpredictable. If you supply more
arguments than conversion specifications, the extra argument values are
simply ignored; this is sometimes useful.
