I understand that due to different arithmetic used in floating points they are just approximations. Hence, 180/100=1 in my python interpreter. How can I tackle this problem of inaccurate floating point numbers? thank you
In the current Python versions (2.2 and up), 180/100 means integer division (because both operands are integer). If you want a floating point result, use 180.0/100 or float(some_variable)/100
Starting with Python 3.0, the / operator will return a floating point result ("true division"). So in that Python version, 180/100 gives 1.8 To enable that behavior on Python 2.x, execute "from __future__ import division":
180/100
1
from __future__ import division 180/100
1.8 In any Python version, 180//100 always means integer division:
180//100
