Fixed point mathematics are mainly used on real-time systems, for low-level graphics operations, or on terminals with low CPU power. Main reason to this is that fixed point maths use INTEGER type for all calculations even divisions, cosines, sinus and square root. You'll never need FLOAT types or Math CPU.
 Useful tools before start
- Cosines tables - full 8 bit circle (0-255)
- Tangents tables - half 8 bit circle (0-127)
- Inverse cosines tables - range from -1 to 1
