Why is 0.1 + 0.2 = 0.30000000000000004 in Python?

Question

Instead of 0.3

Answer 1

i suggest you read up on this:

https://en.m.wikipedia.org/wiki/Floating-point_arithmetic

or a shorter explaination here

https://www.quora.com/Why-is-0-1+0-2-not-equal-to-0-3-in-most-programming-languages

Answer 2

It is also explained here:
https://docs.python.org/2/tutorial/floatingpoint.html

Answer 3

Well, I think you got the answer but if you don't want any trouble during calculations.. you can use something like this..

a = "%0.2f"%(0.1+0.2)
print(a)

where 0.2 indicates that you need answer only upto two decimal places

Answer 4

Floating point. Their inaccurate.

Answer 5

This is probably because 0.1 and 0.2 are floats.
