Python has many inbuilt function.
|round(number[, ndigits])||rounds the number, you can also specify precision in the second argument|
|pow(a, b)||Returns a raise to the power of b|
|abs(x)||Return absolute value of x|
|max(x1, x2, …, xn)||Returns largest value among supplied arguments|
|min(x1, x2, …, xn)||Returns smallest value among supplied arguments|
Below mentioned functions are in math module, so you need to import math module first, using the following line.
|ceil(x)||This function rounds the number up and returns its nearest integer|
|floor(x)||This function rounds the down up and returns its nearest integer|
|sqrt(x)||Returns the square root of the number|
|sin(x)||Returns sin of x where x is in radian|
|cos(x)||Returns cosine of x where x is in radian|
|tan(x)||Returns tangent of x where x is in radian|
Let’s take some examples to understand better
>>> abs(-22) # Returns the absolute value
>>> max(9, 3, 12, 81) # Returns the maximum number
>>> min(78, 99, 12, 32) # Returns the minimum number
>>> pow(8, 2) # can also be written as 8 ** 2
>>> pow(4.1, 3.2) # can also be written as 4.1 ** 3.2
>>> round(5.32) # Rounds to its nearest integer
>>> round(3.1456875712, 3) # Return number with 3 digits after decimal point
>>> import math
