# Rounding of Decimals

#### Flow chart in rounding of numbers.

Examples:
1. Round 56.2435 to the nearest hundredths
1. Identify the digit to be rounded off
2. 4
3. Digit at the right side of the identified digit.
4. 3, less than 5
5. Drop all the digits to the right side of the identified digit, thus;
6. 56.2400 is the rounded value.
2. Round 50.7365 to the nearest hundredths
1. Identify the digit to be rounded off
2. 3
3. Digit at the right side of the identified digit.
4. 6, greater than 5. Thus 3 will become 4 and the sum is not 10.
5. Drop all the digits to the right side of the identified digit, thus;
6. 50.7400 is the rounded value.
3. Round 188.4983 to the nearest hundredths
1. Identify the digit to be rounded off
2. 9
3. Digit at the right side of the identified digit.
4. 8, greater than 5. Thus 9 will become 10, since the sum is 10 add 1 to the right side of the rounded number thus 4 become 5.
5. Drop all the digits to the right side of the identified digit, thus;
6. 188.5000 is the rounded value.
4. Round 199.9983 to the nearest hundredths
1. Identify the digit to be rounded off
2. 9
3. Digit at the right side of the identified digit.
4. 9, greater than 5. Thus 9 will become 10, since the sum is 10 add 1 to the right side of the rounded number thus 9 becomes 10. Again since the sum is 10 repeat the process until the sum is not 10.
5. Drop all the digits to the right side of the identified digit, thus;
6. 200.0000 is the rounded value.
