A division of 7/3 in Python will gives a result of 2. However, this is not correct. Since Python always assume that the numbers are whole numbers, the result will be truncated from 2.5 to 2.
A work around is to write one or both of the numbers as a decimal:
1 2 3 4 5 6 7 8 | >>> print 7/3.0 2.5 >>> print 7.0/3 2.5 >>> print 7.0/3.0 2.5 |
In order to change this behaviour of Python, throughout the program execution, so that Python will always produce real numbers, a module division has to be imported.
1 2 3 4 | >>> from __future__ import division >>> print 7/3 2.5 |
