REALTYPE, intent(in) :: a,bOUTPUT PARAMETERS:
integer, intent(out) :: idumDESCRIPTION:
This routine is a kind of dummy routine primarily to provide a means to spot NaN values. Output is 1 or 2, based on which is smaller (a or b, respectively). The default is 2, and the idea is that "imin=2" should be returned also if a is NaN. If b=HUGE(b), then this provides a means to detect if a is a denormal number.
