F ® 0 ® 1 ® 2 ® 3 ® 4 ® 6 ® A ® AII ® F ® 0 ® 1. Displays the specified
decimal point or add mode.
Valid only when the [ /L
Sets the specified decimal point. If no specification, floating is set.
When processing floating point data, the operation result is zero-shifted.
When A mode is specified, key-entered data are multiplied by 1/100 only when the
key-entered numerical value is used for addition/subtraction or memory
addition/subtraction. If the [/] key is pressed during data entry, A mode is invalid.
The operation result is treated the same as the specified decimal point, 2. When
AII mode is specified, key-entered data are multiplied by 1/100 only when the
key-entered numerical value is used for multiplication/division by [=] key. If the [/]
key is pressed during data entry, AII mode is invalid. The operation result is
treated the same as the specified decimal point, 2.
half-adjusts. When a decimal point is specified, the digit (s) in the subsequent
decimal place is (are) half-adjusted, rounded-off, or rounded-up (??).
If floating point is specified, the value of the least significant digits which cannot
be displayed is rounded off.

[DEC] keys are valid. When the [ /L
[CUT], [UP], and [0, 1, 2, 3, 4, 6, A, AII] lock keys are valid.
When the [SETI/SETII] lock key is on, prints and express the stored tax rate.
When the [SETI/SETII] lock key is off, store the expression data to the new tax
rate. The result of tax rate is only floating-point, and not consent the decimal-point
at this function.
(after approx. 6 minutes.)
When the [2 TAX] lock key is on, one tax rate can be set. (SETII and TAXII will be
disabled.)
When the [2 TAX] lock key is off, two tax rates can be set.
When the [2 M] lock key is on, one memory can be used. (MII will be disabled.)
When the [2 M] lock key is off, two memories can be used.
