In real work
Drill: floor prices with ROUNDDOWN from memory. Discount floors in Indore markets and Chicago outlets. Mixed ₹ and $. Classroom drill: write three brand-new ROUNDDOWN formulas on a blank sheet using names from your own city — if you can invent them without the page open, you own the skill. Then break one formula on purpose and watch the error; recovering from that break is half of interview readiness. Always verify with a known case before trusting a long chain. Keep a personal notebook of the one mistake you make most often with this function; review it monthly.
