Because they are not the same inputs.
11 is an integer and 11.0 is a float and Python (along with many 
programming languages) treats division slightly differently for
ints and floats. You can bypass this by making your divisor a
float:

######
def f(y):
      return (y/5.0)*2*(np.pi)*0.2
##########


Now it will return the same result regardless of int or float.

In Python v3 this is the default behavior
