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.

uTo 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.

uTo 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.

0229 To calculate 101112 + 110102

0230 To calculate (118 + 78)2

0231 Perform the calculation 12310 + 10102 so it produces a hexadecimal result

Bitwise Operations

The logical operators (and, or, xor, not) can be used in calculations.

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

or......

Returns the result of a bitwise sum.

xor ....

Returns the result of a bitwise exclusive logical sum.

not ....

Returns the result of a complement (bitwise inversion).
