Is there a formula within Quickbase that would calculate the miles from one point to another if the latitude and longitude were supplied for two locations?

FWIW here is a comparison of the coefficients when the formulas are aligned to the same structure:

((62.9536940934*($OriginLat - $DestLat)^2 + (48.3428337241*($OriginLong - $DestLong))^2)^0.5

((69*($OriginLat - $DestLat))^2 + (53*($OriginLong - $DestLong))^2)^0.5
