2.4 BINARY, OCTAL, DECIMAL, HEXADECIMAL CALCULATIONS
Binary, octal, decimal and hexadecimal calculations, conversions and logical operations are performed in the
G
BASE-N mode (
The number system (2,8,10,16) is set by respectively pressing
G
by . A corresponding symbol – "b", "o", "d" or "h" appears on the display.
EXE
Number systems are specified for specific values by pressing
G
(b, o, d, or h), immediately followed by the value.
General function calculations cannot be performed in the BASE-N mode.
G
Only integers can be handled in the BASE-N mode. If a calculation produces a result that includes a decimal
G
value, the decimal portion is cut off.
Octal, decimal and hexadecimal calculations can be handled up to 32 bits, while binary can be handled up
G
to 12 bits.
