Question

explain 10 math function used in python​

Answer 1

Answer:

List of Functions in Python Math Module

Function Description

ceil(x) Returns the smallest integer greater than or equal to x.

copysign(x, y) Returns x with the sign of y

fabs(x) Returns the absolute value of x

factorial(x) Returns the factorial of x

floor(x) Returns the largest integer less than or equal to x

fmod(x, y) Returns the remainder when x is divided by y

frexp(x) Returns the mantissa and exponent of x as the pair (m, e)

fsum(iterable) Returns an accurate floating point sum of values in the iterable

isfinite(x) Returns True if x is neither an infinity nor a NaN (Not a Number)

Answer 2

Answer:

The math module is a standard module in Python and is always available. To use mathematical functions under this module, you have to import the module using import math.

It gives access to the underlying C library functions. For example,

# Square root calculation

import math

math.sqrt(4)

This module does not support complex datatypes. The cmath module is the complex counterpart.
