Program example
In the program example shown below, the SIN
−1
value of data (binary floating point) stored in D0 and D1 is calculated,
and the angle is output in 4-digit BCD to Y040 to Y057 when X000 turns ON.
Operation when "0.5" is stored in D0 and D1
The angle (in radians) is calculated by the SIN
−
1
operation ([1]).
The value in radians is converted into the value in
degrees ([2]).
The angle expressed in binary floating point (real
number) is converted into an integer (binary) ([3]).
