Python | Numpy np.assert_almost_equal() method (original) (raw)

Last Updated : 30 Jan, 2020

With the help of **np.assert_almost_equal()** method, we can get the assertion error if two items are not equal up to desired precision value by using np.assert_almost_equal() method.

Syntax : np.assert_almost_equal(actual, desired, decimal)
Return : Return the assertion error if two values are not equal.

Example #1 :
In this example we can see that by using np.assert_almost_equal() method, we are able to get the assertion error if two values are not equal up to a precision value by using this method.

import numpy as np

import numpy.testing as npt

gfg = npt.assert_almost_equal( 1.2222222222 , 1.2222222222 , decimal = 5 )

print (gfg)

Output :

Nope

Example #2 :

import numpy as np

import numpy.testing as npt

gfg = npt.assert_almost_equal( 1.2222222222 , 1.2223422222 , decimal = 5 )

print (gfg)

Output :

AssertionError:
Arrays are not almost equal to 5 decimals
ACTUAL: 1.2222222222
DESIRED: 1.2223422222
