Description
SIN of the value specified in S+1 and S is calculated, and the result [an angle (radians)] is stored in D+1 and
D.
−1
SIN
([S+1, S]) → [D+1, D]
Specifying the integer device with [S], the integer data is internally converted to real numbers before
operations continue.
R0
F317 ASIN, % DT 0, DT 4
Specifying the integer device with [D], the real numbers are automatically converted into integer data.
R0
F317 ASIN, DT 0, % DT 4
When the constant K is specified in S, the operations are the same as when a integer device is specified.
