		real(dp), intent(in)	b )

compare two double precision reals

Parameters

a	first number to compare
b	second number to compare

Returns

0 if a == b 1 if a > b -1 if a < b

cmp_i4()

pure integer function, public ppm_compare::cmp_i4	(	integer(i4), intent(in)	a,
		integer(i4), intent(in)	b )

compare two integers

Parameters

a	first number to compare
b	second number to compare

Returns

0 if a == b 1 if a > b -1 if a < b

cmp_i4_indirect_dp()

compare two integers indirectly

Parameters

a	first index to compare
b	second index to compare
indirection	table to reference for values

Returns

0 if indirection(a) == indirection(b) 1 if indirection(a) > indirection(b) -1 if indirection(a) < indirection(b)
