PetscScalarPrecision#

Names of the floating-point precisions that a PetscScalar could in principle be built with

Synopsis#

typedef enum {
  PETSC_SCALAR_DOUBLE,
  PETSC_SCALAR_SINGLE,
  PETSC_SCALAR_LONG_DOUBLE,
  PETSC_SCALAR_HALF
} PetscScalarPrecision;

Values#

PETSC_SCALAR_DOUBLE - IEEE double precision
PETSC_SCALAR_SINGLE - IEEE single precision
PETSC_SCALAR_LONG_DOUBLE - C long double precision
PETSC_SCALAR_HALF - IEEE half precision

Note#

This enum is reserved for situations where an object might be created in a precision different from PetscScalar; the current PETSc code does not use it.
