PetscIntSumTruncate#
Computes the sum of two positive PetscInt
and truncates the value to slightly less than the maximal possible value
Synopsis#
static inline PetscInt PetscIntSumTruncate(PetscInt a, PetscInt b)
Not Collective; No Fortran Support
Input Parameters#
a - the
PetscInt
valueb - the second value
Returns#
The result as a PetscInt
value
Notes#
Use PetscInt64Mult()
to compute the product of two PetscInt
as a PetscInt64
Use PetscRealIntMultTruncate()
to compute the product of a PetscReal
and a PetscInt
and truncate to fit a PetscInt
Use PetscIntMultError()
to compute the product of two PetscInt
if you wish to generate an error if the result will not fit in a PetscInt
Developer Note#
This is used where we compute approximate sizes for workspace and need to insure the workspace is index-able.
