CInt96 - 96 bit integer data type

Postby Josep Roca » Sep 15, 2018 1:05

This is my attempt to implement a 96-bit data type for Free Basic. It uses a DECIMAL structure with a scale of 0 to store the values. It supports up to 29 significant digits and can represent values in excess of 7.9228 x 10^28. The largest possible value is +/-79,228,162,514,264,337,593,543,950,335.

Thanks to the overloading feature of Free Basic, you can use it as the other available numeric data types, e.g.

Code: Select all

DIM int96 AS CInt96 = 1234567890
int96 = int96 + 111
int96 = int96 - 111
int96 = int96 * 2
int96 = int96 / 2
int96 += 123
int96 -= 123
int96 *= 2
int96 /= 2


Because the bigger numeric variable natively supported by Free Basic is a long integer, if we want to set bigger values we need to use strings, e.g.

Code: Select all

DIM int96 AS CInt96 = "79228162514264337593543950335"


Documentation: https://github.com/JoseRoca/WinFBX/blob ... 20Class.md

BTW my WinFBX framework implements other data types such Currency, Decimal, Variant, Safe Array and Dictionary (associative arrays), but I'm posting this one here because it doesn't need the framework.

Save the following code as CInt96.bi (or CInt96.inc or whatever you like). To use it, just use #include "CInt96.bi".

Code: Select all

Why 96 bit and not 128 bit?
For scientific calculations the maximum is a bit limited. It can contain avogrado's constant, but not the mass of the sun in kg.

Because the Windows API functions that I have used don't allow more. The DECIMAL structure uses 12 bytes to store the number, an UBYTE for the sign and another UBYTE for the scale.

Code: Select all

type tagDEC
   wReserved as USHORT

   union
      type
         scale as UBYTE
         sign as UBYTE
      end type

      signscale as USHORT
   end union

   Hi32 as ULONG

   union
      type
         Lo32 as ULONG
         Mid32 as ULONG
      end type

      Lo64 as ULONGLONG
   end union
end type

type DECIMAL as tagDEC

José are these early days for this project? I was thinking of the bitwise operations, shr and so on.

I have implemented all I can. If somebody is able to overload the bitwise operators to work with these big numbers it will be a very welcome addition. Arithmetic shift is no my speciality.

I will experiment to see if I can implement ^, AND, OR, XOR, EQV, IMP and MOD. I have had a crazy idea that maybe will work. SHR and SHL are beyond my knowledge.

for anyone interested, the Decimal type is defined in wtypes.bi, for convenience I paste the definition below

Code: Select all

type tagDEC
   wReserved as USHORT

   union
      type
         scale as UBYTE
         sign as UBYTE
      end type

      signscale as USHORT
   end union

   Hi32 as ULONG

   union
      type
         Lo32 as ULONG
         Mid32 as ULONG
      end type

      Lo64 as ULONGLONG
   end union
end type

type DECIMAL as tagDEC

type LongLong is 64-bit or LongInt
so if you have

Code: Select all

#Include "cint.bas"
Dim big as Cint96

big = 9223372036854775807 ' Max Longint value
big *= 7
Print big
print "big.scale = ";big.m_int96.scale      ''Ubyte
print "big.sign = ";big.m_int96.sign         ''Ubyte
print "big.signscale = ";big.m_int96.signscale   ''Ushort
print "big.Hi32 = ";big.m_int96.Hi32         ''Ulong
print "big.Mid32 = ";big.m_int96.Mid32      ''Ulong
print "big.Lo64 = ";big.m_int96.Lo64         ''UlongInt
Sleep

knowing how to access the Decimal components, it should be straightforward to implement the desired bit functions

@deltarho[1859]
to shift a dec value by 1 should be straightforward, it would be something like this
not tested

Code: Select all

Dim as Cint96 big, tmp
Dim carry as ulong

carry=bit( big.m_int96.Lo64, 63 )
tmp.m_int96.Lo64 = big.m_int96.Lo64 shl 1
tmp.m_int96.Hi32 = (big.m_int96.Hi32 shl 1) or carry

I am not sure that's right but it should be something like that, it's of course more complicated if you want to shift by more than 1
to shift right, you do something like the following
not tested

Code: Select all

Dim as Cint96 big, tmp
Dim carry as ulong

carry=bit( big.Hi32, 0 )
tmp.Hi32 = big.m_int96.Hi32 shr 1
tmp.m_int96.Lo64  = big.m_int96.Lo64  shr 1
if carry then
   tmp.m_int96.Lo64 or=&h8000000000000000ULL
end if

Hi32 is not a datatype but the name of a member of the DECIMAL structure and is an ULONG.

BTW my crazy idea does not work. The API functions involved overflow with these big numbers.

with the help of stack overflow here's the shift left function, it certainly needs to be optimized but am under the weather and not up to par
the right shift function should be similar

About your previous remark but now suppressed (code works with "Return' but not with 'Function ='):
- 'Return' calls the copy-constructor while 'Function =' calls the let-operator but as the two procedures have the same code, so the problem is not coming for here!
- The other difference between 'Return' and 'Function' is that 'Return' exits the procedure but not 'Function ='.
Therefore you must add 'exit function' after the first two 'Function =' (the last being the final instruction):

Code: Select all

function shift_left96(byval n as CInt96, byval k as long) as CInt96
   dim as ulong a, b, c
   a=n.m_int96.Hi32
   b=n.m_int96.Mid32
   c=(n.m_int96.Lo64 shl 32 ) shr 32
   if k<=96 then
      if k>=32 then
         a=b
         b=c
         c=0
         n.m_int96.Hi32=a
         n.m_int96.Lo64=c
         n.m_int96.Mid32=b
         function = shift_left96(n,k-32)
         exit function
      else
         if k=0 then
            function = n
            exit function
         else
            a=(a shl k) or (b shr (32 - k))
            b = (b shl k) or (c shr (32 - k))
            c = c shl k
           
            n.m_int96.Hi32=a
            n.m_int96.Lo64=c
            n.m_int96.Mid32=b
         end if
      end if
   end if
   function = n
end function
