gmp_libmpn_divexact_1 Method |
Divide {sp, n} by d, expecting it to divide exactly, and writing the result to {rrp, n}.
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 void mpn_divexact_1(
mp_ptr rp,
mp_ptr sp,
mp_size_t n,
mp_limb_t d
)
Public Shared Sub mpn_divexact_1 (
rp As mp_ptr,
sp As mp_ptr,
n As mp_size_t,
d As mp_limb_t
)
public:
static void mpn_divexact_1(
mp_ptr^ rp,
mp_ptr^ sp,
mp_size_t n,
mp_limb_t d
)
static member mpn_divexact_1 :
rp : mp_ptr *
sp : mp_ptr *
n : mp_size_t *
d : mp_limb_t -> unit
Parameters
- rp
- Type: Math.Gmp.Nativemp_ptr
The result integer. - sp
- Type: Math.Gmp.Nativemp_ptr
The first operand integer. - n
- Type: Math.Gmp.Nativemp_size_t
The number of limbs in sp and rp. - d
- Type: Math.Gmp.Nativemp_limb_t
The second operand integer.
Remarks
If d doesn’t divide exactly, the value written to {rp, n} is undefined.
The areas at rp and sp have to be identical or completely separate, not partially overlapping.
Examples
mp_ptr sp = new mp_ptr(new uint[] { 0xffffffff, 0x0000ffff });
mp_ptr rp = new mp_ptr(new uint[2]);
mp_ptr result = new mp_ptr(new uint[] { 0x55555555, 0x00005555 });
gmp_lib.mpn_divexact_1(rp, sp, sp.Size, 0x3);
Assert.IsTrue(rp.SequenceEqual(result));
gmp_lib.free(rp, sp, result);
Dim sp As New mp_ptr(New UInteger() { &HffffffffUI, &Hffff})
Dim rp As New mp_ptr(New UInteger(1) { })
Dim result As New mp_ptr(New UInteger() { &H55555555, &H5555})
gmp_lib.mpn_divexact_1(rp, sp, sp.Size, &H3)
Assert.IsTrue(rp.SequenceEqual(result))
gmp_lib.free(rp, sp, result)
