In python a number of mathematical operations can be performed with ease by importing a module named “math” which defines various functions which makes our tasks easier.
1. ceil() :- This function returns the smallest integral value greater than the number. If number is already integer, same number is returned.
2. floor() :- This function returns the greatest integral value smaller than the number. If number is already integer, same number is returned.
The ceil of 2.3 is : 3 The floor of 2.3 is : 2
3. fabs() :- This function returns the absolute value of the number.
4. factorial() :- This function returns the factorial of the number. An error message is displayed if number is not integral.
The absolute value of -10 is : 10.0 The factorial of 5 is : 120
5. copysign(a, b) :- This function returns the number with the value of ‘a’ but with the sign of ‘b’. The returned value is float type.
6. gcd() :- This function is used to compute the greatest common divisor of 2 numbers mentioned in its arguments. This function works in python 3.5 and above.
The copysigned value of -10 and 5.5 is : -5.5 The gcd of 5 and 15 is : 5
