Priority in Manual Calculatio ns
In the BASIC
mode, you
can type in formulas in the
exact
order
in
which
they are
written,
including
parentheses
or functions. The
order
of priority
in
catcul
a tion and
treatment
of
intermediate results will be taken care of by the
computer i
t
self.
The internal order
of
priority
in
manual calculations
is
as
follows:
1)
Recalling variables or
re.
2)
Functions
(SIN, COS,
etc.)
3) Power ("')
and power root (ROT)
4)
Signs(+,-)
5)
Multiplication and division
(*,
I
)
6) Addition and subtraction
(
+,
-
)
7) Comparison of magnitude(>,>=,<,<=,<>)
8)
Logical
operations
(AND,
OR, NOT, and XOR)
Notes:
•
If
parentheses
are
used
in
a formula, the operation
given
within
the
parentheses
has
the highest priority.
•Composite functions are operated from
right
to left (sin
cos:"
0.6).
•
Chained power
(3
42
or
3"" 4"2)
or
power root are operated from right to
left.
•
For
the above items
3)
and
4),
the last entry
in
the calculation formula has
a higher
priori
t
y.
(e.g.) -2
A
