+|Two sets of coordinates x1,y1 x2,y2| |''x1 y1 x2 y2-- f1 ''|
+=== Description ===
+Calculates the distance between two map points (x1,y1) to (x2,y2) and pushes the resulting floating point number to the stack.
+=== Examples ===
+<code>
+#Terrain modification script to build a circular pyramid.
+#Keep in mind modifying terrain on a large scale like this can lag the game badly for a short moment, so not recommended to do this mid-level unless you slow the loops.
+$radius:30
+$stepWidth:3.0
+$min:1
+$max:10

+			<-centerX add(I) ->x
+			<-centerY add(J) ->y
+			distance(CurrentCoords <-x <-y) ->dist
+			#Finds what height to set terrain to. Step width divides the height and as a result makes each pyramid step wider. Also rounds up the current value.
+			ceil(<-radius sub(<-dist) div(<-stepWidth)) ->height
+			#Caps the terrain to a minimum of 1 and a maximum of 10. Interestingly, the maximum can be set to above its current value if you want a volcano formation.
