The implementation function is double Power (double base, int exponent), which is the exponent of the base. You must not use library functions, and you do not need to consider large number problems.The first thing you can think of is that if

Getting started with matlab-numerical calculation
All of MATLAB's operations are based on matrices, and most of the data in MATLAB is almost always matrices. In the following introduction, mainly from these aspects of MATLAB basic numerical
1. Common Code for decimal number
Commonly used code of the decimal number includes 8421bcd code, remaining 3 code, and Gray code. The encoding principle is to convert the decimal 0 ~ 9. Each of the 10 Base numbers uses a 4-bit binary code instead
IEEE754 the representation of floating-point numbers. The expression range of float type data in C language is -3.4*10^38~+3.4*10^38. Double is -1.7*10^-308~1.7*10^308,long double for -1.2*10^-4932~1.2*10^4932.
Number of bits
We have briefly introduced the binary number system. We will not go into detail here. The computer can only recognize binary systems. We know that a computer is composed of multiple electronic components, and the electronic components
Just as we have to decide whether a quantity uses integers or real numbers, and how many ranges we use, we have to decide for ourselves if a certain quantity needs positive or negative. If this quantity does not have a negative value, then we can
