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

Remark
Fractions can be converted to
decimals and then converted
back to fractions.
Fractions and improper
fractions which can be reduced
become reduced fractions when
a calculation command key is
press.
Press
to convert
to improper fraction.
When the total number of
characters, including integer,
numerator, denominator and
delimiter mark exceeds 10, the
input fraction is automatically
displayed in decimal format.
Calculations containing both
fractions and decimals are
calculated in decimal forma.
Fractional calculations can
be performed by using
parentheses in the numerator or
denominator.
