Gail: Thanks for the response.
So, If I were to use decimal for this application to store frequencies in the format of 0000.0000, I would need decimal (8, 4) Correct. Like using Numeric (8,4). For the purposes of frequencies, with a possible need to do addition/subtraction of standard offsets say 6Mhz, which data type should I use? Is there a benefit of one over the other in this application?
