18.34.16      MAP_ROUNDING

MAP_ROUNDING Real

Maximum error which can be tolerated between optimal size ( given by MAP_FIELD/MAP_CELL) and its rounded value MAP_SIZE (as a power of 2k̂ 3p̂ 5q̂) when rounding by floor (thus limiting the field of view). If the rounding error becomes larger, rounding is made by ceiling, which guarantees a larger field of view, but leads to bigger images.

Default is 0.05.
