[mapserver-users] How can I avoid long notation of double values in label or info template for shapes?

[Havard Tveite]

According to http://www.mapserver.org/mapfile/class.html

TEXT ("Area is: " + tostring([area],"%.2f"))

could also be used.

round and tostring are documented in http://www.mapserver.org/mapfile/expressions.html

round ( n1 , n2 )

tostring ( n1, "Format1" )
