DVP-ES3 Series Programming Manual Symbol S ： Source value D ： Arccosine value Explanation 1. This instruction finds the arccosine of the value in S and stores it in D . Arccosine value=cos -1 The following graph shows the relation between cosine and arccosine values. _6 2. If the absolute value of the conversion result is larger than the value that can be represented by the maximum floating-point number, SM602 is ON. 3. If the absolute value of the conversion result is less than the value that can be represented by the minimum floating-point number, SM601 is ON. 4. If the conversion result is zero, SM600 is ON.
