SIND, SINDP
(2) Angles designated at are set in radian units (degrees / 180).
For conversion between degrees and radian values, see the RADD and DEGD instructions.
(3) When the operation results in -0 or an underflow, the result is processed as 0.
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 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.
