C++ algorithm for division between 2 signed integer intervals
Consider intervals A = [x1, y1] and B = [x2, y2], two intervals representing signed integers.
Interval arithmetic page on Wikipedia gives a formula to address the case where B does not contain 0, whose C++ implementation may be as follows:
void…
