7.12 Special function instructions 7.12.2 SIND, SINDP
Program Example
(1) The following program conducts a SIN operation on the angles stored in the four BCD digits from X20 to X2F and stores
the results at D0 and D1 as 32-bit floating decimal point type real numbers.
[Ladder Mode]
[List Mode]
[Operations involved when X20 to X2F designate a value of 150]
: Angle data of which the SIN (sine) value is obtained or head number of the devices where the angle data is stored (real number)
: Head number of the devices where the operation result will be stored (real number)
Function
(1) The SIN (sine) value of the angle specified by is calculated and its result is stored into the device specified by .
