Rounding

You can be asked to round to the nearest:

• the nearest whole number,
• the nearest ten/ hundred etc,
• a specified number of decimal places,
• a specified number of significant figures
357.956 to 2 decimal places

To round: mark where you are rounding to.

357.956

If the next number down is 5 or more, your marked number goes up one. 357.956

357.96 to 2 dp.

357.956 to 1 decimal places

357.956

358.0 to 1 dp.

The 0 is important

1359.834
• 1359.83 to 2 dp
• 1359.8 to 1dp
• 1360 to nearest whole number
• 1360 to nearest ten
• 1400 to nearest hundred
• 1000 to nearest thousand
Significant figures
• The furthest left non zero number is your first significant figure.
• e.g 596.32 0.003296 4002
• The next one right is the second sig fig and so on.

3rd sig fig

4002

2nd sig fig

1st sig fig

To 3 Significant figures
• 596.32 = 596
• 0.003296 = 0.00330
• 4002 = 4000
• So a number to 3 significant figures can have more than 3 digits if zeros are required to keep the value of the number
