The default base is 10 for decimals, but you can change it to any other value from 2 upwards.
All proper fractions are input as decimal numbers.
It is only the radix fractions that are given in the
specified base.
A
decimal fraction in any base other than 10 is called
a radix fraction here.
For example, 0.101
_{2} is the base-2 (binary) radix fraction form of the proper fraction
^{5}/
_{8}
and similarly 0.47
_{8} is the base-8 (octal) radix fraction for
^{39}/
_{64}.
The "digits" of numbers in
a base bigger than 10 are each shown as a separate
decimal number
with each column (place) separated by a space.
For example:
^{11}/_{12} + ^{1}/_{122} in base 12 is shown as | 0 . | 11 | 1 |
^{1}/_{12} + ^{1}/_{122} in base 12 is shown as | 0 . | 1 | 1 |
^{11}/_{122} in base 12 is shown as | 0 . | 0 | 11 |
