Python: int(3.0) = 2

Question

Observe the following python program

def goo(y,x):
    y = float(y)
    x = float(x)
    yup = (y - x - 1) / x
    yup = str(yup)
    yup = yup.split(\".\")
             


        

Answer 1

The default for the print statement is to round the value to the nearest. int() truncates.

>>> print 2.99999999999999
3.0
>>> print int(2.99999999999999)
2

If you want to see a more exact representation, use repr.

>>> print repr(2.9999999999999)
2.9999999999999
