[M*] ...................... Prints and displays the result of memory calculation and automatically feeds
[M*¹]..................... Operates both [M¹] and [M*] key operations. Pressing this key once is equivalent
[´, ¸]...................... If the multiplication or division instruction is stored in memory, prints the
[=].......................... Executes a stored multiplication/division instruction, rounds the result to the
[%]......................... If an arithmetic instruction is stored in memory, performs percentage calculation,
[MU/D].................. If a multiplication/division instruction is stored in memory, cancels the data.
paper one line. In item count mode, prints the contents of the item counter for
memory before the calculation result printing. After the [M*] key operation, the
contents of memory and the contents of the item counter for memory are cleared.
Contents of the data register or stored arithmetic instruction are not changed.
to pressing the [M¹] key; pressing the key twice is the same as pressing the [M*]
key.
operators, performs the operations and displays the results while simultaneously
storing a new arithmetic instruction in memory. The decimal point for the result is
floating. If the [´] or [¸] key is pressed in constant calculation mode, prints the
displayed numeric value without performing an operation and stores a new
multiplication/division instruction in memory.
specified number of decimal places, prints and displays the result, then
automatically feeds the paper one line. Stores the multiplicand or divisor together
with constant calculation mode in memory. If an instruction is not stored in
memory, no operation is performed and the previous state is held. Pressing the [=]
key immediately after the [´] or [¸] key performs the following operation.
rounds the result to the specified number of decimal places, prints and displays the
result. Stores the multiplicand/divisor together with constant calculation mode in
memory. If a percentage calculation for multiplication is performed, percent
discount/add-on calculation can be done by using the [+] or [-] key. At that time,
addition/subtraction using the addition/subtraction register is not performed. If an
arithmetic instruction is not stored in memory, no operation is performed and the
previous state is held. Pressing the [%] key immediately after the [´] or [¸] key
performs the following operation.
% key operation example: percent discount/add-on calculation
The decimal point for the result is floating.
MU/D key operation example:
a ´ =.......aa
a ¸ =.......1
a ´ % = ...aa/100
a ¸ % = ...100
a ´ b%....ab/100
+.............a + (ab/100)
c% ..........ac/100
+.............a + (ac/100)
a ´ b%....ab/100
-.............a - (ab/100)
c% ..........ac/100
-.............a - (ac/100)
aMU/Db =................. a/(1 - (b/100)) - a
aMU/Db +/- =........... a/(1 + (b/100)) - a
c =................. a/(1 - (c/100)) - a
c +/- =........... a/(1 + (c/100)) - a
9
a/(1 - (b/100))
a/(1 - (c/100))
a/(1 + (b/100))
a/(1 + (c/100))
