+|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
+-> centerX
+-> centerY
+-> height
+do (<- height add(1) <-height mul(-1))
+  do (<-height add(1) <-height mul(-1))
+    <-centerX add(I) ->x
+    <-centerY add(J) ->y
+    distance( <-x <-y <-height sub(<-dist))
