Is it possible to write infinities to fields in arc feature classes, and if so, how?
Currently I get an exception thrown when I try.
Float in ArcGIS has a range of values. Infinity values are not supported. You can store such values in 3rd party non ESRI applications and attempt to import but these values will be changed to 1.#INF -1.#INF and you may encounter problems with Querying, etc.
