* arts-2-1-464

	* src/check_input.cc (chk_atm_field, chk_atm_surface):
	Replaced all checks for fabs(a-b)>0 (in checking constancy at poles and
	cyclicity at longitudes) by is_same_within_epsilon(a,b,2*DBL_EPSILON) to
	avoid number accuracy issues.

	* src/logic.cc (is_same_within_epsilon): Minor bug fix (correct handling
	of negative numbers)

	* src/methods.cc,workspace.cc: Cosmetics.

	* src/m_atmosphere.cc (basics_checkedCalc): Cosmetics.
