[BangPypers] strange behavior

[Sidharth Kuruvila]

Any number with a decimal point is treated as an object of type float and
the numbers without a decimal point of are treated as ints. You can use the
type function to find the type of an object.

>>> type(1)
<type 'int'>
>>> type(1.0)
<type 'float'>

>>> 1+1.0
2.0
Arithmetic operations over two types give the result in the more flexible
type, in this case that is a float.

You can use the int and float functions for type conversion

>>> int(1.0)
1
>>> float(1)
1.0
