Detailed Description

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

The input value must be greater than 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 ACosHOperator() applied (orange):

Actual Processing Code of the ACosHOperator

unsigned int ACosHOperator<double>::Process()
{
  double out = acosh((double)m_input);
  m_output = out;

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