Program Example
(1) The program example below calculates the SIN of 3-digit BCD data designated by X20 to
X2B, and outputs a 1-digit BCD part to the integer part from Y50 to Y53, and a 4-digit BCD
fraction part from Y40 to Y4F.
Y60 is turned ON if the results of the operation are negative. (If a value has been set at X20
to X2F that is greater than 360, it will be adjusted to be in the range from 0 to 360.)
