7.12.2 SIN operation on floating-point data (Double precision) (SIND(P))
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 to D3 as 64-bit floating decimal point type real
numbers.
[Ladder Mode]
[List Mode]
[Operations involved when X20 to X2F designate a value of 150]
Inputs an angle used for
SIN operation ( ).
Converts the input angle into a
64-bit floating-point real number ( ).
Converts the converted angle
into a radian value ( ).
Executes SIN operati
on using the
converted radian value ( )
