#### Obase

-- Option variable: obase Default value: 10

`obase` is the base for integers displayed by Maxima.

`obase` may be assigned any integer between 2 and 36 (decimal), inclusive. When `obase` is greater than 10, the numerals comprise the decimal numerals 0 through 9 plus capital letters of the alphabet A, B, C, ..., as needed. A leading 0 digit is displayed if the leading digit is otherwise a letter. The numerals for base 36, the largest acceptable base, comprise 0 through 9, and A through Z.

See also `ibase`.

Examples:

```          (%i1) obase : 2;
(%o1)                          10
(%i2) 2^8 - 1;
(%o10)                      11111111
(%i3) obase : 8;
