The math library functions abs, sqrt, max, and min are used in programming to perform mathematical operations on numbers.
- abs: The abs function returns the absolute value of a number, which is the magnitude of the number without regard to its sign. For example, abs(-5) returns 5.
- sqrt: The sqrt function returns the square root of a number. For example, sqrt(25) returns 5.
- max: The max function returns the maximum value from a set of numbers. For example, max(2, 5, 7) returns 7.
- min: The min function returns the minimum value from a set of numbers. For example, min(2, 5, 7) returns 2.
These functions are commonly used in programming for a variety of applications, such as calculating distances, finding the maximum or minimum value in a dataset, or performing numerical operations.
