conversion to real => DBLE (including real part of a complex number) conversion to complex => CMPLX complex conjugate => CONJG imaginary part => AIMAG All functions are uppercase. CMPLX is preprocessed by f_defs.h and performs an explicit cast: #define CMPLX(a,b) cmplx(a,b,kind=DP) This implies that 1) f_defs.h must be included whenever a CMPLX is present, 2) CMPLX should stay in a single line, 3) DP must be defined. All occurrences of real, float, dreal, dfloat, dconjg, dimag, dcmplx removed - please do not reintroduce any of them. Tested only with ifc7 and g95 - beware unintended side effects Maybe not the best solution (explicit casts everywhere would be better) but it can be easily changed with a script if the need arises. The following code might be used to test for possible trouble: program test_intrinsic implicit none integer, parameter :: dp = selected_real_kind(14,200) real (kind=dp) :: a = 0.123456789012345_dp real (kind=dp) :: b = 0.987654321098765_dp complex (kind=dp) :: c = ( 0.123456789012345_dp, 0.987654321098765_dp) print *, ' A = ', a print *, ' DBLE(A)= ', DBLE(a) print *, ' C = ', c print *, 'CONJG(C)= ', CONJG(c) print *, 'DBLE(c),AIMAG(C) = ', DBLE(c), AIMAG(c) print *, 'CMPLX(A,B,kind=dp)= ', CMPLX( a, b, kind=dp) end program test_intrinsic Note that CMPLX and REAL without a cast yield single precision numbers on ifc7 and g95 !!! git-svn-id: http://qeforge.qe-forge.org/svn/q-e/trunk/espresso@2133 c92efa57-630b-4861-b058-cf58834340f0 |
