Overwriting the Operator
The trigonometric functions either work with degree or radian. The currently
active unit can be seen in the status display. "DEG" stands for degree, "RAD"
for radian. You can switch between the angle units by using the <RAD> and/or
<DEG> keys. Switch-over of the angle unit is accompanied by a new labelling
of the function keys relating to the angle unit according to the new status.
You can convert a display value into degree or radian as follows:
1.
Adjust the currently set angle unit to the unit that you associate with the
display value. For converting a value from degree into radian, click on
"RAD", otherwise on "DEG".
2.
Now press "2nd" and "►rad" or "►deg" for the actual conversion. As for
each other function, the result is displayed immediately.
Using the key sequence "2nd" "%", the displayed figure is converted from a
figure into a percentage by dividing it by 100.
If "%" is pressed after an arithmetic operation, additions, reductions and per‐
centages can be calculated as follows:
●
Adding an addition, i.e. addition of n% to x: x "+" n "%" "="
●
Settling a reduction, i.e. subtraction of n% from x: x "-" n "%" "="
●
Multiplication by a percentage, multiplication of x by n%: x "×" n "%" "="
●
Division by a percentage, i.e. division of x by n%: x "÷" n "%" "=".
As opposed to squaring and extracting the square root, the exponentiation and
root extraction with any exponent do not constitute a function. The exponen‐
tiation/root extraction is an operator analog to those for the basic arithmetic
operations and for the performance, you need a first and a second operand. In
the exponentiation, the first operand is the base and the second one the expo‐
nent. In the root extraction, the operands are called radicand and exponent of
a root.
For the exponentiation xⁿ, you enter x "xⁿ" n, for the root ⁿ√x analogously x
"2nd" "ⁿ√x" n. Here, you can use brackets, as well if the operands consist of an
expression.
In the classic operating mode, the calculator only offers the constant π (Pi) that
can be activated using the "π" key or the <P> shortcut.
Errors and Correcting Entries
Error
Errors in the calculation can be caused by:
●
an undefined operation,
●
a function call with inadmissible argument or
●
by a number overflow in the final or an interim result.
In all these situations, "Error" appears in the display in order to signal the error
status. Afterwards, the error must be deleted before you can continue working.
The calculator including the stored interim results and the repetition memory is
reset using the "C" key or the <Del> shortcut. The same operation is to be used
for deleting an error. The reset will not influence the memory or the set modes.
Using the "CE" key, the display value is deleted without the interim results and
the entered operands being lost. After the "CE" key resetting the display to 0,
continue by once again entering the operand.
Operators that have been entered wrongly by accident cannot be deleted. It is,
however, possible to enter the correct modifier directly after having entered the
wrong one. Thus, the operator is overwritten. This correction possibility applies
to "+", "-", "×", "÷" "xⁿ" and "ⁿ√x".
