Distance in Doom RL is measured according to the so-called Angband metric. In short, distance is the long axis plus half the short axis. The result is always rounded down.
The Angband metric is intended to approximate the usual Euclidean metric. If we round the Euclidean metric to the nearest integer, then the comparison is as follows. Up to a radius of 3, the metrics coincide exactly. Up to a radius of 12, the difference is within 1. In general (ignoring rounding), the Angband metric is always greater than the Euclidean metric, but not more than 12% greater.
