The only solution I saw was for > the user > to do the cast explicitly > We're not saying PetscPowScalar(base,(int)i) is necessarily bad, but we think #if defined(PETSC_USE_64BIT_INDICES) typedef int PowInt; #else typedef PetscInt PowInt; #endif is a pretty ugly way to spell typedef int PowInt; /* explanation why */ or even just calling PetscPowScalar(base,(int)i) instead of PetscPowScalar(base,(PowInt)i). -------------- next part -------------- An HTML attachment was scrubbed...
