Calculation priority
Calculation priority is automatically determined by
the calculator. Algebraic expressions are entered as
they would be written.
Single variable functions and calculations in
parenthesis have a higher priority than basic func-
tions like +, -, x, ÷.
During calculations lower priority calculations are
stored in the stack memory and processed in turn.
Six levels of calculations may be stored in stack
memory.
Calculation range
A maximum of 9 digits in the mantissa or 10 digits
plus 2 digits for exponent may be entered. If a result
is too large to display, an Error indicator appears.
This applies for Decimal/Octal/Hexadecimal modes.
Statistical calculations
Press
to enter Statistical Mode. This clears
MODE 5
all function commands and all registers except the
memory.
The results of statistical calculations are stopped in
the statistical calculation memory. As a result, you
can perform statistical calculations again by exiting
to another mode and then resetting the calculator for
statistical calculation mode.
