What is the result of the following JavaScript code snippet? console.log(0.1 + 0.2 === 0.3);

Explanation

JavaScript uses IEEE 754 double-precision floating-point numbers. Because 0.1 and 0.2 cannot be represented precisely in binary, their sum results in a tiny rounding error (approximately 0.30000000000000004), making the strict equality comparison with 0.3 return false.

Key points

Floating-point math in JS is imprecise
IEEE 754 standard causes binary representation errors
Strict equality checks fail on floating-point sums
