Digit-by-digit algorithms are computational methods used primarily to perform arithmetic operations such as addition, subtraction, multiplication, and division on numbers, particularly large numbers, by processing one digit at a time. These algorithms can be especially useful in contexts where numbers cannot be easily handled by conventional data types due to their size, such as in cryptography or arbitrary-precision arithmetic. ### Key Characteristics 1.
The BKM algorithm (BKM stands for "Baker-Kearfott-Madani") is commonly associated with numerical methods for solving systems of equations, particularly for problems involving interval arithmetic or global optimization. It is designed to provide guaranteed bounds on the solutions of nonlinear equations. While details can vary between implementations, the BKM algorithm primarily focuses on the following: 1. **Interval Arithmetic**: It operates using intervals instead of precise numbers, which allows for capturing uncertainty and rounding errors in computations.
CORDIC, which stands for COordinate Rotation DIgital Computer, is an algorithm used for calculating trigonometric functions, hyperbolic functions, exponentials, logarithms, and square roots, among other operations. It was first introduced by Volder in 1959 and has become a popular method for implementing these calculations in hardware, particularly in dedicated digital processors and embedded systems where resources are limited.
