PetscIntCast#

casts a PetscInt64 (which is 64 bits in size) to a PetscInt (which may be 32-bits in size), generates an error if the PetscInt is not large enough to hold the number.

Synopsis#

static inline PetscErrorCode PetscIntCast(PetscInt64 a, PetscInt *b)

Not Collective; No Fortran Support

Input Parameter#

  • a - the PetscInt64 value

Output Parameter#

Note#

If integers needed for the applications are too large to fit in 32-bit ints you can ./configure using --with-64-bit-indices to make PetscInt use 64-bit integers
