gmp_libmpn_sec_div_r Method |
Set R to N modulo D, where N = {np, nn}, D = {dp, dn}, and R = {np, dn}.
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_sec_div_r(
mp_ptr np,
mp_size_t nn,
mp_ptr dp,
mp_size_t dn,
mp_ptr tp
)
Public Shared Sub mpn_sec_div_r (
np As mp_ptr,
nn As mp_size_t,
dp As mp_ptr,
dn As mp_size_t,
tp As mp_ptr
)
public:
static void mpn_sec_div_r(
mp_ptr^ np,
mp_size_t nn,
mp_ptr^ dp,
mp_size_t dn,
mp_ptr^ tp
)
static member mpn_sec_div_r :
np : mp_ptr *
nn : mp_size_t *
dp : mp_ptr *
dn : mp_size_t *
tp : mp_ptr -> unit
Parameters
- np
- Type: Math.Gmp.Nativemp_ptr
The first operand and result integer. - nn
- Type: Math.Gmp.Nativemp_size_t
The number of limbs of np. - dp
- Type: Math.Gmp.Nativemp_ptr
The second operand integer - dn
- Type: Math.Gmp.Nativemp_size_t
The number of limbs of dp. - tp
- Type: Math.Gmp.Nativemp_ptr
The scratch operand integer.
Remarks
It is required that nn ≥ dn ≥ 1,
and that dp[dn - 1] ≠ 0.
This does not imply that N ≥ D since N might be zero-padded.
Note the overlapping between N and R.
No other operand overlapping is allowed.
The entire space occupied by N is overwritten.
This function requires scratch space of mpn_sec_div_r_itch(nn, dn)
limbs to be passed in the tp parameter.
Examples
mp_ptr np = new mp_ptr(new uint[] { 0xffffffff, 0x0000ffff });
mp_ptr dp = new mp_ptr(new uint[] { 0x00000004 });
mp_size_t size = gmp_lib.mpn_sec_div_r_itch(np.Size, dp.Size);
mp_ptr tp = new mp_ptr(size);
gmp_lib.mpn_sec_div_r(np, np.Size, dp, dp.Size, tp);
Assert.IsTrue(np[0] == 3);
gmp_lib.free(np, dp, tp);
Dim np As New mp_ptr(New UInteger() { &HffffffffUI, &Hffff})
Dim dp As New mp_ptr(New UInteger() { &H4})
Dim size As mp_size_t = gmp_lib.mpn_sec_div_r_itch(np.Size, dp.Size)
Dim tp As New mp_ptr(size)
gmp_lib.mpn_sec_div_r(np, np.Size, dp, dp.Size, tp)
Assert.IsTrue(np(0) = 3)
gmp_lib.free(np, dp, tp)
