static member mpn_divrem_1 :

Parameters
- r1p
- Type: Math.Gmp.Nativemp_ptr
- qxn
- Type: Math.Gmp.Nativemp_size_t
- s2p
- Type: Math.Gmp.Nativemp_ptr
- s2n
- Type: Math.Gmp.Nativemp_size_t
- s3limb
- Type: Math.Gmp.Nativemp_limb_t
Return Value
Type:
mp_limb_tReturn the remainder.
Remarks
The integer quotient is written to {r1p + qxn, s2n}
and in addition qxn fraction limbs are developed and written to {r1p, qxn}.
Either or both s2n and qxn can be zero.
For most usages, qxn will be zero.
mpn_divmod_1 exists for upward source compatibility and is simply a macro
calling mpn_divrem_1 with a qxn of 0.
The areas at r1p and s2p have to be identical or
completely separate, not partially overlapping.
Examples
mp_ptr s2p = new mp_ptr(new uint[] { 0xffffffff, 0x0000ffff });
mp_ptr r1p = new mp_ptr(new uint[2]);
mp_ptr result = new mp_ptr(new uint[] { 0x435e50d7, 0x00000d79 });
mp_limb_t remainder = gmp_lib.mpn_divrem_1(r1p, 0, s2p, s2p.Size, 0x13);
Assert.IsTrue(remainder == 10);
Assert.IsTrue(r1p.SequenceEqual(result));
gmp_lib.free(r1p, s2p, result);
Dim s2p As New mp_ptr(New UInteger() { &HffffffffUI, &Hffff})
Dim r1p As New mp_ptr(New UInteger(1) { })
Dim result As New mp_ptr(New UInteger() { &H435e50d7, &Hd79})
Dim remainder As mp_limb_t = gmp_lib.mpn_divrem_1(r1p, 0, s2p, s2p.Size, &H13)
Assert.IsTrue(remainder = 10)
Assert.IsTrue(r1p.SequenceEqual(result))
gmp_lib.free(r1p, s2p, result)
