mathmatics Gcd () is a function of Python, which is used to calculate the greatest common divisor (GCD) of two integers. This function belongs to Python's math module, so we need to use math.gcd () to call it.
The greatest common divisor is the approximate number of two or more integers. In mathematics, this concept is used to solve various problems, such as simplifying fractions or generating * * * shared keys in cryptography.
The math.gcd () function has two parameters, both of which are integers. The returned result is the greatest common divisor of these two integers.
What is a mathematical function?
Math is the standard library of Python, which provides a set of mathematical functions and constants. This module supports floating-point numbers and complex numbers, and is the standard mathematical library after Python2.2.
Mathematical module contains some commonly used mathematical functions, such as square root, logarithm, trigonometric function, and some useful constants, such as pi and natural logarithm e.
The names of functions and constants of math module are consistent with the standard mathematical symbols, so that mathematical expressions can be expressed in Python in the form of mathematical formulas. This makes Python a convenient language for mathematical calculation and scientific calculation.
In addition, the math module also provides some underlying functions, such as math.sqrt () for calculating the square root, math.sin () for calculating the sine value, and math.exp () for calculating the exponential function. These functions take one parameter (and in some cases two parameters) and return a result.
Math module also contains some useful constants, such as math.pi for pi and math.e for natural logarithm e, which can be directly used in mathematical calculation.
In a word, math module is a very useful standard library in Python, which provides a set of mathematical functions and constants to facilitate mathematical and scientific calculations.
