FAQ
Frequently asked questions
What formula is this based on?
The Pythagorean theorem, applied to the horizontal and vertical differences between the two points.
Can coordinates be negative?
Yes, any real numbers are supported for all four coordinates.
What if the two points are the same?
The distance will be 0.
Does this work in 3D?
No, this calculates distance on a 2D plane. 3D distance would need a z-coordinate too.
