Function mul

Multiplies two intervals, an explanation of all the possible cases ca be found on Interval Arithmetic: from Principles to Implementation - T. Hickey, Q. Ju, M.H. van Emden

Example

Interval.multiply(
 Interval(1, 2),
 Interval(2, 3)
) // Interval(prev(2), next(6))

Example

Interval.multiply(
 Interval(1, Infinity),
 Interval(4, 6)
) // Interval(prev(4), Infinity)

Example

Interval.multiply(
 Interval(1, 2),
 Interval(-3, -2)
) // Interval(prev(-6), next(-2))

Example

Interval.multiply(
 Interval(1, 2),
 Interval(-2, 3)
) // Interval(prev(-4), next(6))

Example

Interval.multiply(
 Interval(-2, -1),
 Interval(-3, -2)
) // Interval(prev(2), next(6))
