Python Math ModulePython math module is defined as the most famous mathematical functions, which includes trigonometric functions, representation functions, logarithmic functions, etc. Furthermore, it also defines two mathematical constants, i.e., Pie and Euler number, etc. Pie (n): It is a well-known mathematical constant and defined as the ratio of circumstance to the diameter of a circle. Its value is 3.141592653589793. Euler's number(e): It is defined as the base of the natural logarithmic, and its value is 2.718281828459045. There are different math modules which are given below: math.log()This method returns the natural logarithm of a given number. It is calculated to the base e. Example
import math
number = 2e-7 # small value of of x
print('log(fabs(x), base) is :', math.log(math.fabs(number), 10))
Output: log(fabs(x), base) is : -6.698970004336019 math.log10()This method returns base 10 logarithm of the given number and called the standard logarithm. Example
import math
x=13 # small value of of x
print('log10(x) is :', math.log10(x))
Output: log10(x) is : 1.1139433523068367 math.exp()This method returns a floating-point number after raising e to the given number. Example
import math
number = 5e-2 # small value of of x
print('The given number (x) is :', number)
print('e^x (using exp() function) is :', math.exp(number)-1)
Output: The given number (x) is : 0.05 e^x (using exp() function) is : 0.05127109637602412 math.pow(x,y)This method returns the power of the x corresponding to the value of y. If value of x is negative or y is not integer value than it raises a ValueError. Example
import math
number = math.pow(10,2)
print("The power of number:",number)
Output: The power of number: 100.0 math.floor(x)This method returns the floor value of the x. It returns the less than or equal value to x. Example:
import math
number = math.floor(10.25201)
print("The floor value is:",number)
Output: The floor value is: 10 math.ceil(x)This method returns the ceil value of the x. It returns the greater than or equal value to x.
import math
number = math.ceil(10.25201)
print("The floor value is:",number)
Output: The floor value is: 11 math.fabs(x)This method returns the absolute value of x.
import math
number = math.fabs(10.001)
print("The floor absolute is:",number)
Output: The absolute value is: 10.001 math.factorial()This method returns the factorial of the given number x. If x is not integral, it raises a ValueError. Example
import math
number = math.factorial(7)
print("The factorial of number:",number)
Output: The factorial of number: 5040 math.modf(x)This method returns the fractional and integer parts of x. It carries the sign of x is float. Example
import math
number = math.modf(44.5)
print("The modf of number:",number)
Output: The modf of number: (0.5, 44.0) Python provides the several math modules which can perform the complex task in single-line of code. In this tutorial, we have discussed a few important math modules.
