The Math module implements a number of mathematical functions for floating-point numbers. These functions are generally a simple encapsulation of functions of the same name in the Platform C Library, so the results of calculations under different platforms may be slightly different and sometimes even very large. The Python math function must import

The behavior of an object in Python is determined by its type (type). The so-called type is support for certain operations. Numeric objects are basic elements in any programming language and support math operations such as add, subtract, multiply, and divide. Python's numeric objects have integers and floating-point numbers, and support various mathematical operations such as +,-,*,/etc. Without these opera
