Built-in Mathematical Functions

Following mathematical functions are built into the Python interpreter, hence you don't need to import them from any module.

Sr.No.	Function & Description
1	Python abs() function The abs() function returns the absolute value of x, i.e. the positive distance between x and zero.
2	Python max() function The max() function returns the largest of its arguments or largest number from the iterable (list or tuple).
3	Python min() function The function min() returns the smallest of its arguments i.e. the value closest to negative infinity, or smallest number from the iterable (list or tuple)
4	Python pow() function The pow() function returns x raised to y. It is equivalent to xy. The function has third optional argument mod. If given, it returns (xy) % mod value
5	Python round() Function round() is a built-in function in Python. It returns x rounded to n digits from the decimal point.
6	Python sum() function The sum() function returns the sum of all numeric items in any iterable (list or tuple). An optional start argument is 0 by default. If given, the numbers in the list are added to start value.
