ACos

(Engine-Level Function)

Description: Calculates the trigonometric arc cosine in radians.
Returns: Numeric
Usage: Script or steady state.
Function Groups: Trigonometric Math
Related to: ASin | ATan | Cos | Sin | Tan
Format: ACos(X)
Parameters:  
X
Required. Any numeric expression in the range -1 to +1.
Comments:

The returned angle is in radians. To convert an angle from radians to degrees, divide by \Pi / 180 or (approximately) 0.0174533.

\Pi is a defined constant in VTScada.

Example:

  RadAngle = ACos(0);
  DegAngle = RadAngle / \Pi / 180;

In this example, the value of DegAngle will be 90.
