Numbers that neither begin with ‘<samp>0</samp>’ or ‘<samp>0x</samp>’, nor end with a ‘<samp>.</samp>’ are, by default, entered in base 10; likewise, the default display for numbers—when no particular format is specified—is base 10. You can change the default base for both input and output with the commands described below. </p> <dl compact="compact"> <dd><a name="index-set-input_002dradix"></a> </dd> <dt><code>set input-radix <var>base</var></code></dt> <dd><p>Set the default base for numeric input.

On the other hand, ‘<samp>set input-radix 10</samp>’ leaves the input radix unchanged, no matter what it was, since ‘<samp>10</samp>’, being without any leading or trailing signs of its base, is interpreted in the current radix. Thus, if the current radix is 16, ‘<samp>10</samp>’ is interpreted in hex, i.e. as 16 decimal, which doesn’t change the radix. </p> <a name="index-set-output_002dradix"></a> </dd> <dt><code>set output-radix <var>base</var></code></dt> <dd><p>Set the default base for numeric display.
