Understanding Floating-Point Precision Issues in JavaScript (0.1+0.2 vs 0.3+0.4)

JavaScript’s unexpected result for 0.1 + 0.2 versus the exact 0.3 + 0.4 arises because numbers are stored in IEEE‑754 double‑precision binary, where limited mantissa bits require exponent alignment and rounding (ties‑to‑even), causing small representation errors that appear as 0.30000000000000004.
