Chapter 2: Main Application 58
Selecting a Number Base
Specifying a default number base in the Main application will apply to the current line (expression/result pair),
and to all subsequent lines until you change the default number base setting.
u To select the number base for the line where the cursor is located
1. Tap the down arrow button next to the < button.
2. Tap the button that corresponds to the number base you want to use:
1 (binary), 2 (octal), 3 (decimal), 4 (hexadecimal).
• The currently selected number base is indicated in the status bar.
3. Execute the calculation.
Important!
• A line for which a number base is not specified is called a “normal calculation line”. To return a line to a
normal calculation line, tap < in step 2 of the above procedure.
• Calculation results produced by a line for which a number base is specified are followed by one of the suffixes
listed below, to indicate its number system.
Number System Binary Octal Decimal Hexadecimal
Suffix b o d h
u To specify a number base for an input value
You can input the following suffixes to specify the number base of a value as you input it: [b] (binary), [o] (octal),
[d] (decimal), and [h] (hexadecimal). You can specify a number base for an input value only when a default
number base (besides normal) is selected
Arithmetic Operations
You can use the following operators when performing binary, octal, decimal and hexadecimal values: +, −, ×, ÷,
^. You can also use parenthetical expressions.

and ...Returns the result of a bitwise product.
or ......Returns the result of a bitwise sum.
