Python | sympy.evalf() method

Last Updated : 18 Jun, 2019

With the help of sympy.evalf() method, we are able to evaluate the mathematical expressions.

Syntax : sympy.evalf() Return : Return the evaluated mathematical expression.

Example #1 : In this example we can see that by using sympy.evalf() method, we are able to evaluate the mathematical expressions.

Python3 1=1

# Import sympy
from sympy import *

# Use sympy.evalf() method
expn = sqrt(9)
gfg = expn.evalf()

print(gfg)

Output :

3.00000000000000

Example #2 :

Python3 1=1

# Import sympy
from sympy import *

# Use sympy.evalf() method
expn = sqrt(9)*cos(45)
gfg = expn.evalf()

print(gfg)

Output :

1.57596596645319
