Types of numbers
- one dimensional number ( 1D)
- two dimensional number (2D) = complex numbers.
It represents point on 2D plane.
- ( There are no 3D numbers)
- hypercomplex number
- four dimensional number (4D)= = quaterions = Hamilton number
- eight dimensional number (8D) = octonions= Cayley number
- sedenions (16D)
- trigintaduonions (32D)

Type {integer numbers}
{from unit bitmaps XPERT software production Tamer Fakhoury}
- _bit = $00000000..$00000001; number 1 bit without sign = (0..1) }
- _byte = $00000000..$000000FF; number 1 byte without sign = (0..255)}
- _word = $00000000..$0000FFFF; number 2 bytes without sign = (0..65 535)}
- _dWord = $00000000..$7FFFFFFF; number 4 bytes without sign= (0..4 294 967 296)}
- _longInt = $80000000..$7FFFFFFF; number 4 bytes with sign = (-2 147 483 648..2 147 483 648}
The computers doesen't know what means binary code until You tell him what type of number it is. Diffrent types give diffrent decimal numbers from one binary number.

How to deal with complex numbers
- without explicit definition
- using variant type: Borland unit VarCmplx ( very simple for education but so slow !!!)
- using assembler optimized code:
- using pointer type: unit ComplexRec by R.Tschaggelar - last updated: 21.dec.99. Pointer because function can give only "one" value. Read disclaimer !
- using record type:
