acos()

The hec-python-library equivalent of Jython method acos():

Not Implemented

This method is not implemented in release 1.1

The following example performs the equivalent:

# ts is a TimeSeries object
import numpy as np

ts.data["value"] = np.arccos(ts.data["value"])

Warning

Directly manipulating the TimeSeries data property bypasses built-in consistency mechanisms. The user must ensure that the time series Parameter (including unit) and ParameterType are updated if necessary.
