Math module is a standard in-built module in Python that can be used for performing the mathematical tasks. The math module has a set of methods and constants.
Note: For more information, refer to Math-library-functions
1. Python math.e constant: The math.e constant returns the Euler’s number: 2.71828182846.
Syntax: math.e
Returns: Return a float value, 2.71828182846, representing the mathematical constant e
Example:
# Import math Library import math # Print the value of Euler e print (math.e) |
Output:
2.718281828459045
2. Python math.pi constant: The math.pi constant returns the value pi: 3.14159265359. It is defined as the ratio of the circumference to the diameter of a circle.
Syntax: math.pi
Returns: A float value, 3.14159265359, representing the mathematical constant PI
Example:
# Import math Library import math # Print the value of pi print (math.pi) |
Output:
3.141592653589793
3. Python math.tau constant: The math.tau constant returns the value tau: 6.283185307179586. It is defined as the ratio of the circumference to the radius of a circle.
Syntax: math.tau
Returns: A float value, 6.283185307179586, representing the mathematical constant tau
Example:
# Import math Library import math # Print the value of tau print (math.tau) |
Output:
6.283185307179586
4. Python math.inf constant: The math.inf constant returns of positive infinity.
For negative infinity, use -math.inf.The inf constant is equivalent to float(“inf”).
Syntax: math.inf
Returns: A float value, returns the value of positive infinity.
Example:
# Import math Library import math # Print the positive infinity print (math.inf) # Print the negative infinity print (-math.inf) |
Output:
inf -inf
5. Python math.nan constant: The math.nan constant returns a floating-point nan (Not a Number) value. This value is not a legal number.The nan constant is equivalent to float(“nan”).
Syntax: math.nan
Returns: A float value, nan (Not a Number)
Example:
# Import math Library import math # Print the value of nan print (math.nan) |
Output:
nan
