4.0,3.0,5.0,2.0,6.0,7.0,8.0.

to break results down, want result pattern display database results closest number input(4.0),then next result, if available, lower 1 degree(3.0), higher 1 degree(5.0),then lower 2 degrees (2.0), , higher 2 degrees(6.0). 7.0 , 8.0 numbers displayed numerically because there no lows match them.
