gmp_libmpz_getlimbn Method |
Return limb number n from op.
Namespace:
Math.Gmp.Native
Assembly:
Math.Gmp.Native (in Math.Gmp.Native.dll) Version: 1.0.0.0 (1.0.0.0)
Syntax public static mp_limb_t mpz_getlimbn(
mpz_t op,
mp_size_t n
)
Public Shared Function mpz_getlimbn (
op As mpz_t,
n As mp_size_t
) As mp_limb_t
public:
static mp_limb_t mpz_getlimbn(
mpz_t^ op,
mp_size_t n
)
static member mpz_getlimbn :
op : mpz_t *
n : mp_size_t -> mp_limb_t
Parameters
- op
- Type: Math.Gmp.Nativempz_t
The operand integer. - n
- Type: Math.Gmp.Nativemp_size_t
The zero-based limb index.
Return Value
Type:
mp_limb_tThe limb number
n from
op.
Remarks
The sign of op is ignored, just the absolute value is used.
The least significant limb is number 0.
mpz_size can be used to find how many limbs make up op.
mpz_getlimbn returns zero if n is outside the range 0
to mpz_size(op) - 1.
Examples
mpz_t op = new mpz_t();
char_ptr value = new char_ptr("1000 ABCD 1234 7AB8 24FD");
