Mathematical Functions:

Function	Returns (description)
Abs(x)	The absolute value of x: the (positive) distance between x and zero.
Ceil(x)	The ceiling of x: the smallest integer not less than x
Cmp(x, y)	-1 if x<y, 0 if x==y, or 1 if x>y
Exp()	The exponential of x:ex
Fabs(x)	The absolute value of x.
Floor(x)	The floor of x: the largest integer not greater than x
Log(x)	The natural logarithm of x, for x>0
Log10(x)	The base-10 logarithm of x, for x>0
Max(x1,x2,…)	The largest of its arguments: the value closest to positive infinity
Min(x1,x2,…)	The smallest of its arguments: the value closest to negative infinity
Modf(x)	The fractional and integer parts of x in a two-item tuple. Both parts have the same sign as x. the integer part is returned as a float.
Pow(x,y)	The value of x**y
Round(x [,n])	X rounded to n digits from the decimal point. Python rounds away from zero as a tie-breaker
Sqrt(x)	The square root of x for x>0
