Numbers that neither begin with ‘<samp>0</samp>’ or 79‘<samp>0x</samp>’, nor end with a ‘<samp>.</samp>’ are, by default, entered in base 8010; likewise, the default display for numbers—when no particular 81format is specified—is base 10. You can change the default base for 82both input and output with the commands described below. 83</p> 84<dl compact="compact"> 85<dd><a name="index-set-input_002dradix"></a> 86</dd> 87<dt><code>set input-radix <var>base</var></code></dt> 88<dd><p>Set the default base for numeric input.

On the other hand, ‘<samp>set input-radix 10</samp>’ 100leaves the input radix unchanged, no matter what it was, since 101‘<samp>10</samp>’, being without any leading or trailing signs of its base, is 102interpreted in the current radix. Thus, if the current radix is 16, 103‘<samp>10</samp>’ is interpreted in hex, i.e. as 16 decimal, which doesn’t 104change the radix. 105</p> 106<a name="index-set-output_002dradix"></a> 107</dd> 108<dt><code>set output-radix <var>base</var></code></dt> 109<dd><p>Set the default base for numeric display.
