<h4 class="subsection">14.2.14 Numeric Input Conversions</h4>
<p>This section describes the <code>scanf</code> conversions for reading numeric
values.
<p>The ‘<samp><span class="samp">%d</span></samp>’ conversion matches an optionally signed integer in decimal
radix.
<p>The ‘<samp><span class="samp">%i</span></samp>’ conversion matches an optionally signed integer in any of
the formats that the C language defines for specifying an integer
constant.
<p>For example, any of the strings ‘<samp><span class="samp">10</span></samp>’, ‘<samp><span class="samp">0xa</span></samp>’, or ‘<samp><span class="samp">012</span></samp>’
could be read in as integers under the ‘<samp><span class="samp">%i</span></samp>’ conversion. Each of
these specifies a number with decimal value <code>10</code>.
<p>The ‘<samp><span class="samp">%o</span></samp>’, ‘<samp><span class="samp">%u</span></samp>’, and ‘<samp><span class="samp">%x</span></samp>’ conversions match unsigned
integers in octal, decimal, and hexadecimal radices, respectively.
<p>The ‘<samp><span class="samp">%X</span></samp>’ conversion is identical to the ‘<samp><span class="samp">%x</span></samp>’ conversion. They
both permit either uppercase or lowercase letters to be used as digits.
<p>Unlike the C language <code>scanf</code>, Octave ignores the ‘<samp><span class="samp">h</span></samp>’,
‘<samp><span class="samp">l</span></samp>’, and ‘<samp><span class="samp">L</span></samp>’ modifiers.
