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

private

Set the units of the application of this operator.

This method is used for the relational operators.  It ignores the
given units, and instead ensures that all operands have the same
units.  The units it chooses are those that are 'least' amongst the
possibilities for the operand units, i.e. that have the smallest
multiplicative factor when expanded.
