Python integer division retains two decimal places

In the PY application there are many numbers in the results of the operation, it is inevitable that the division (such as unit conversion, etc.), but the integer after the operation will only return an integer, the general results need to be accurate to the next two bits, at this time you can use the following two ways to solve:

1. Convert any integer that participates in the operation to the float type explicitly as follows:

def convert_unit (num_size): Return round ((float (num_size)/1048576), 2)

2. Importing the Division method can also be implemented

From __future__ Import Division def convert_unit (num_size): Return round (num_size/1048576), 2)

Integer operation results will have decimal digits after importing this method, no need to explicitly convert float type
