WebA fixed-point machine, it can be used to process algorithms traditionally implemented in floating-point math. We discuss the issues that are important in implementing an algorithm in fixed-point math. There are robust procedures for understanding how to do this. We describe useful principles and practices. WebA translation is an affine transformation with no fixed points. Matrix multiplications always have the origin as a fixed point. Nevertheless, there is a common workaround using homogeneous coordinates to represent a translation of a vector space with matrix multiplication: Write the 3-dimensional vector using 4 homogeneous coordinates as .
