Rounding off

• In rounding off a number is made simpler by keeping its value intact but closer to the next number.
• It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.
• Rounding off numbers is done to preserve the significant figures.
• If the digit in the smallest place is less than 5, then the digit is left untouched. Any number of digits after that number becomes zero and this is known as rounding down.
• If the digit in the smallest place is greater than or equal to 5, then the digit is added with +1. Any digits after that number will become zero, this is known as rounding up.

Checking the round-off for given numbers:

• 842 → Round off to the nearest 10 → 800
• 9537 → Round off to nearest 100 → 9500
• 49730 → Round off to nearest 1000 → 50000
• 2546 → Round off to nearest 100 → 2500
• 286 → Round off to nearest 100 → 300
• 5750 → Round off to nearest 100 → 5800
• 168 → Round off to nearest 100 → 200
• 149 → Round off to nearest 100 → 100
• 9870 → Round off to nearest 100 → 9900
