Print-resolution examples with exact arithmetic
Follow a 3000 × 2000 image and an A4 target through exact inches, metric conversion, recurring decimals, and whole-pixel ceiling.
Example: A4 at 300 PPI with explicit whole-pixel ceiling
Convert 210 × 297 mm through exact inches and see why minimum-density ceiling gives 2481 × 3508 pixels.
