Notes
• Priority Sequence in Calculation
As
mentioned in the preceding section, calculations are subject
to
the rule
of
"priority sequence" (true algebraic logic) which requires
that
multiplication and
division take precedence over addition and subtraction. This computer auto-
matically judges the priority sequence. You simply input a numeric expression
and the correct answer will be displayed.
Here
is
the priority sequence in a calculation:
1) Functions (sin, cos, tan, etc.)
2)
Power
(t)
3)
Multiplication(*), division(/)
4)
Addition ( +
),
subtraction
(-)
Calculations
are
performed according
to
this priority sequence. When calcula-
tions happen to be equal in the priority sequence, priority
is
given
to
the calcula-
tion on the left.
If
there are parentheses,
top
priority should be given
to
the
parenthesized calculation.
Example:
2+3*SIN(17+13)

and
Calculation Digits
The range
of
input values (number
of
input digits) acceptable
to
this computer
is
12 digits for a mantissa and 2 digits for an exponent.
Th
e same number
of
digits apply
to
internal calculations.
The displayed range
of
a value (number -
of
output
digits)
is
10 digits for a
mantissa and 2 digits for an exponent.
