Question
What is the output of print(0.1 + 0.2 == 0.3
?
Options: Pick one correct answer from below
- True
- False
- Machine Independent
- Error
Solution
Break Down the Problem
- We need to evaluate the expression
0.1 + 0.2 == 0.3
. - Determine whether the result of the addition is equal to
0.3
.
Relevant Concepts
- In many programming languages, floating-point arithmetic can lead to precision issues due to how numbers are represented in binary.
Analysis and Detail
-
Calculate
0.1 + 0.2
:- In binary,
0.1
and0.2
cannot be represented exactly, which may lead to precision loss.
- In binary,
-
The result of
0.1 + 0.2
in Python (and many other programming languages) is approximately0.30000000000000004
instead of exactly0.3
. -
Therefore, comparing this result to
0.3
will yield:
Verify and Summarize
- Since the floating-point representation causes a minor discrepancy, the result of the comparison (
0.1 + 0.2 == 0.3
) will evaluate toFalse
.
Final Answer
The correct answer is False.
