_set_in_units()

def CellMLToNektar.pycml.mathml_root._set_in_units (   self,   units,   no_act = False  )

private

Set the units of the application of this operator.

Set the degree to have units of dimensionless, and the operand to
have an arbitrary member of its possible units set.

Where these mean the <apply> doesn't have the given units, wrap it
in suitable units conversion mathematics.
