Program example
• 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.)
