Base–n calculations
Use MAIN ( [ MODE ] 1 ( MAIN ) ) mode for Base–n calculations.
The unit enables you to calculate in number base other than decimal.
The calculator can add, subtract, multiply, and divide binary, octal, and
hexadecimal numbers.
The following shows the numerals that can be used in each number
base.
Binary base ( b ) : 0, 1
Octal base ( o ) : 0, 1, 2, 3, 4, 5, 6, 7
Decimal base : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Hexadecimal base ( h ) : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F
