**************************************************
Python Mathematical Functions:
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
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
Example :
＞＞＞ abs(-22)               # Returns the absolute value
22
＞＞＞ max(9, 3, 12, 81)      # Returns the maximum number
81
＞＞＞ min(78, 99, 12, 32)    # Returns the minimum number
12
＞＞＞ pow(8, 2)              # can also be written as 8 ** 2
64
＞＞＞ pow(4.1, 3.2)          # can also be written as 4.1 ** 3.2
91.39203368671122
＞＞＞ round(5.32)            # Rounds to its nearest integer
5
＞＞＞ round(3.1456875712, 3) # Return number with 3 digits after decimal point
