Python Coding Challenge - Question with Answer (ID -220626)

 

Explanation:

Line 1: 0.1 + 0.2

What happens?

Python adds the two floating-point numbers:

0.1 + 0.2

Expected mathematical result

0.3

Actual stored result

Because computers store floating-point numbers in binary, some decimal values cannot be represented exactly.

Internally:

0.1 ≈ 0.10000000000000000555...

0.2 ≈ 0.20000000000000001110...

So:

0.1 + 0.2

becomes approximately:

0.3000000000000000444...

Line 2: == 0.3

What happens?

Python compares:

0.3000000000000000444...

with

0.3

Internally, 0.3 is stored as:

0.2999999999999999888...

So Python checks:

0.3000000000000000444...

==

0.2999999999999999888...

Since these values are not exactly equal:

False

is produced.

Line 3: print(...)

What happens?

The print() function displays the result of the comparison.

print(False)

Output

False
