Let's take the numbers from the previous Time for action tutorial and let the assert_approx_equal
function work on them:
print "Significance 8", np.testing.assert_approx_ equal(0.123456789, 0.123456780, significant=8)
The result is:
Significance 8 None
print "Significance 9", np.testing.assert_approx_equal(0.123456789, 0.123456780, significant=9)
An exception is thrown:
Significance 9 Traceback (most recent call last): ... raiseAssertionError(msg) AssertionError: Items are not equal to 9 significant digits: ACTUAL: 0.123456789 DESIRED: 0.12345678
