Given the first line from a
to b
where a < b
and the second line from x
to y
where x < y
, how do you calculate the intersection length of those two?
Example:
a =0, b=5, x=3, y=7
012345
|----|
|---|
34567
the result would be 2
since they are intersection from 3
to 5
.
Is there an expression with these 4 variables to extract the result? There is no guarantee that there is an intersection nor is it guaranteed that x > a
I have looked at timespan intersection examples but they all have an if
expression in them which is not possible in my situation.
Logic is quite simple:
if (y<a) or (x>b):
return no intersection
intersection.left = max(a, x)
intersectioni.right = min(b, y)
