absolute_finite_non_zeros_range()

Optional[Range] ortools.math_opt.python.statistics.absolute_finite_non_zeros_range

(

Iterable[float]

values

)

Returns the range of the absolute values of the finite non-zeros.

Args:
  values: An iterable object of float values.

merge_optional_ranges()

Optional[Range] ortools.math_opt.python.statistics.merge_optional_ranges	(	Optional[Range]	lhs,
		Optional[Range]	rhs )

Merges the two optional ranges.

Args:
  lhs: The left hand side range.
  rhs: The right hand side range.
