Mathematical Functions in Python | Set 1 (Numeric Functions)

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.

# Python code to demonstrate the working of
# ceil() and floor()
  
# importing "math" for mathematical operations
import math
  
a = 2.3
  
# returning the ceil of 2.3
print ("The ceil of 2.3 is : ", end="")
print (math.ceil(a))
  
# returning the floor of 2.3
print ("The floor of 2.3 is : ", end="")
print (math.floor(a))

Output:

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.

br>

4. factorial() :- This function returns the factorial of the number. An error message is displayed if number is not integral.

# Python code to demonstrate the working of
# fabs() and factorial()
  
# importing "math" for mathematical operations
import math
  
a = -10
  
b= 5
  
# returning the absolute value.
print ("The absolute value of -10 is : ", end="")
print (math.fabs(a))
  
# returning the factorial of 5
print ("The factorial of 5 is : ", end="")
print (math.factorial(b))

Output:

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.

# Python code to demonstrate the working of
# copysign() and gcd()
  
# importing "math" for mathematical operations
import math
  
a = -10
b = 5.5
c = 15
d = 5
  
# returning the copysigned value.
print ("The copysigned value of -10 and 5.5 is : ", end="")
print (math.copysign(5.5, -10))
  
# returning the gcd of 15 and 5
print ("The gcd of 5 and 15 is : ", end="")
print (math.gcd(5,15))

Output:

The copysigned value of -10 and 5.5 is : -5.5
The gcd of 5 and 15 is : 5
