<h4 class="subsection">3.10.1 Constants</h4>

<p><a name="index-integer-notation-489"></a><a name="index-constants-in-linker-scripts-490"></a>All constants are integers.

   <p>As in C, the linker considers an integer beginning with &lsquo;<samp><span class="samp">0</span></samp>&rsquo; to be
octal, and an integer beginning with &lsquo;<samp><span class="samp">0x</span></samp>&rsquo; or &lsquo;<samp><span class="samp">0X</span></samp>&rsquo; to be
hexadecimal.  Alternatively the linker accepts suffixes of &lsquo;<samp><span class="samp">h</span></samp>&rsquo; or
&lsquo;<samp><span class="samp">H</span></samp>&rsquo; for hexadeciaml, &lsquo;<samp><span class="samp">o</span></samp>&rsquo; or &lsquo;<samp><span class="samp">O</span></samp>&rsquo; for octal, &lsquo;<samp><span class="samp">b</span></samp>&rsquo; or
&lsquo;<samp><span class="samp">B</span></samp>&rsquo; for binary and &lsquo;<samp><span class="samp">d</span></samp>&rsquo; or &lsquo;<samp><span class="samp">D</span></samp>&rsquo; for decimal.  Any integer
value without a prefix or a suffix is considered to be decimal.

   <p><a name="index-scaled-integers-491"></a><a name="index-K-and-M-integer-suffixes-492"></a><a name="index-M-and-K-integer-suffixes-493"></a><a name="index-suffixes-for-integers-494"></a><a name="index-integer-suffixes-495"></a>In addition, you can use the suffixes <code>K</code> and <code>M</code> to scale a
constant by
<!-- TEXI2ROFF-KILL -->
<!-- END TEXI2ROFF-KILL -->
<code>1024</code> or <code>1024*1024</code>
<!-- TEXI2ROFF-KILL -->
<!-- END TEXI2ROFF-KILL -->
respectively.  For example, the following
all refer to the same quantity:

<pre class="smallexample">     _fourk_1 = 4K;
     _fourk_2 = 4096;
     _fourk_3 = 0x1000;
     _fourk_4 = 10000o;
</pre>
   <p>Note - the <code>K</code> and <code>M</code> suffixes cannot be used in
conjunction with the base suffixes mentioned above.
