Fixed-point arithmetic

Fixed-point arithmetic is a numerical representation and computation method where numbers are represented with a fixed number of digits before and after the decimal point (or binary point). Unlike floating-point arithmetic, which can represent a wide range of values by using a variable number of significant digits and exponents, fixed-point arithmetic has a predetermined level of precision and range. ### Key Characteristics of Fixed-point Arithmetic: 1. **Representation**: The numbers are represented as integers multiplied by a scaling factor.
