When enabled, the ACOS instruction computes the arc cosine of source and saves the result in Destination (in radians).

 

 

  • The range of source : -1.0 ~ 1.0

  • The result is saved in the Destination (in radians)

(Please refer to RAD or DEG instruction for more details)

 

Example)

If M00 is ON, the ACOS calculates the arc cosine of D100 and saves the result in D90 (Radian value).

The DEG instruction converts Radian value D90 to float value and saves its value to D80.

The INT instruction converts float value D80 to BCD value and saves its value to D70.
