  21    <p>You can always enter numbers in octal, decimal, or hexadecimal in
  22 GDB by the usual conventions: octal numbers begin with
  23 <code>0</code>, decimal numbers end with <code>.</code>, and hexadecimal numbers
  24 begin with <code>0x</code>.  Numbers that begin with none of these are, by
  25 default, entered in base 10; likewise, the default display for
  26 numbers--when no particular format is specified--is base 10.  You can
  27 change the default base for both input and output with the <code>set
  28 radix</code> command.
  29
  30      <dl>
  31 <dt><code>set input-radix </code><var>base</var><code></code>
  32      <dd>Set the default base for numeric input.  Supported choices
  33 for <var>base</var> are decimal 8, 10, or 16.  <var>base</var> must itself be
  34 specified either unambiguously or using the current default radix; for
  35 example, any of
  36
  37      <pre class="smallexample">          set radix 012
  38           set radix 10.
  39           set radix 0xa
  40           </pre>
  41
  42      <p>sets the base to decimal.  On the other hand, <code>set radix 10</code>
  43 leaves the radix unchanged no matter what it was.
  44
  45      <br><dt><code>set output-radix </code><var>base</var><code></code>
  46      <dd>Set the default base for numeric display.  Supported choices
  47 for <var>base</var> are decimal 8, 10, or 16.  <var>base</var> must itself be
  48 specified either unambiguously or using the current default radix.

  50      <br><dt><code>show input-radix</code>
  51      <dd>Display the current default base for numeric input.
  52

  54      <dd>Display the current default base for numeric display.
