Rounding down towards negative infinity. Truncating approximates without rounding. In other words, it “rounds” towards zero. Rounding 3.14159 ≈ 3.1416 Truncating 3.14159 ≈ 3.1415 · Hopefully you get the difference. It makes truncating rarely useful in precise calculations (although JavaScript probably isn’t a good choice at all if you need precise calculations) but you can come across a situation when it may be irreplaceable. Once example can be when needing to drop decimal places from a pixel value to avoid anti aliasing or weird pixel rounding which is completely different across browser engines.
