  "transcript": "\n\n--- Top Comments ---\n\n\n[66 upvotes] GCC, when provided a constant divisor, finds two magic numbers and replaces division with multiplication and a comparison. The succint term for this op is called Reciprocal multiplication.\n\nIt's pretty cool and this obscure paper from 2011 shows one how to derive these magic numbers for division.\n\n[12 upvotes] So is the purpose of this to reduce the difficulties that come with float precision?\n\nEDIT: The comments are informative, if they’re not made by jerks. I clearly have much to learn. I appreciate the patience of those who have it, and wish a very strong “go step on some legos” to those who do not.",
