Editing Decimal separator (section)

===In non-base-10 numbering systems===
In binary (base-2), a full space can be used between groups of four digits, corresponding to a [[nibble]], or equivalently to a [[hexadecimal]] digit. For integer numbers, dots are used as well to separate groups of four bits.{{efn|name="DR-DEBUG_H"|
As an example, the [[DR-DOS]] [[DEBUG (DOS command)|DEBUG]] {{code|H}} command (short for 'hex') displays the entered hexadecimal number in hexadecimal, followed by the same number in decimal, octal, and binary, prefixed with a hash sign ({{code|#}}), backslash ({{code|\}}), and percent sign ({{code|%}}) respectively:
<pre>
-h 1234
1234 #4660 \011064 %0001.0010.0011.0100
</pre>}}
Alternatively, binary digits may be grouped by threes, corresponding to an [[octal]] digit. Similarly, in hexadecimal (base-16), full spaces are usually used to group digits into twos, making each group correspond to a [[byte]].{{efn|name="DR-DEBUG_D"}} Additionally, groups of eight bytes are often separated by a hyphen.{{efn|name="DR-DEBUG_D"|
As an example, the [[DR-DOS]] [[DEBUG (DOS command)|DEBUG]] {{code|D}} command (short for 'dump') dumps the memory byte-wise in hexadecimal notation, with bytes separated by spaces and groups of eight bytes separated by hyphens:
<syntaxhighlight lang="hexdump">
-d 0
