D
(2) A sign for the operation data is set at
If the operation data is a positive value, this is set at "0", and if it is a negative value, it is set at "1".
(3) The part before the decimal point and fraction part are stored at
(Settings can be between 0 and 1.0000.)
(4) Operation results stored at
(5) Calculation results are a value from which the decimal fraction part has been rounded.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into
SD0.

Program Example
(1) The following program performs a SIN
the BCD 1-digit integer part from X30 to X33 and the BCD 4-digit decimal fraction part from X20 to X2F, and outputs the
calculated angle in 4 BCD digits from Y40 to Y4F.
