[dba-SQLServer] C# / SQL Server: select all zips within 5 miles ofa ZIP list

Michael,

Thanks for the suggestion.  Maybe but there are only 6 digits right of the decimal in the zip data. 
  Plus floats are native to hardware whereas (I think) decimals are string manipulation in a 
software library.
