Detailed Description

The ACosOperator is the inverse function of the cosine function and calculates the radian angle for the input cosine value.

The input value must be in the range of -1.0 and 1.0, otherwise the output will be set to NaN (Not-A-Number) and operator processing status will be set to STATUS_ERROR.

Arguments

When operator is used inside a signal its default input is automatically tied to signal's InternalValue or previous operator's output. Its default output is automatically tied to next operator's input or to signal's Value. See also CDP Operator Usage In CDP Signals.

Example

Below is an example plot with linearly increasing signal (cyan) and the same signal with CosHOperator() applied (orange):

Actual Processing Code of the ACosOperator

unsigned int ACosOperator<double>::Process()
{
  double out = acos((double)m_input);
  m_output = out;

  return std::isnan(out)? STATUS_ERROR : STATUS_OK;
}
