In the dictionary entry for $. (sparse) the elaboration of function code 1 states that if e is elided, e is assumed to be "a floating point 0". (The format is 1$.sh;a;e )
I do not understand why floating point is specified here. My understanding is that numeric values are handled in a manner such that the J user (normally) should not put any thought to how a number is implemented. Why does the implementation of zero matter here? If e is explicitly asserted as 0, will it be implemented as binary? What differences may occur if e is specified as 0j0? ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
