If a number is 3.555 what is the rounding rule?

Question

If the 3rd number to the right is 5, does the preceding 5 go up or stay the same?

Answer 1

You always round up from 5. If you want to keep 2 decimal places the number would round up to 3.56. For one decimal place = 3.6. For a whole number = 4

Answer 2

You only round 1 time, and only to a specific decimal value.

So you don't say 3.555, the last 5 rounds up which makes 2nd "5" a "6" etc etc.

Your rounding options for this number are

3.56
3.6
4.0

Answer 3

You always look to the right and round up if you see a 5 or greater. So, depending on how many significant figures you are rounding to, 3.555 would round to:

4, or
3.6, or
3.56

Answer 4

Look to the original equation for the number of decimal places. It really depends on what the number is being used for. Does it make sense to state the figure down to the thousandth or hundredth?

Answer 5

Depends on how many decimal places you want to round to.
To a whole number: 4
To 1 decimal: 3.6
To 2 decimals: 3.56

Answer 6

Add 1 to the preceeding number

Answer 7

One decimal place = 3.6
Two decimal place = 3.56
Or whole number = 4

Answer 8

it will go up and it will be 4

Answer 9

it goes up to 6
so it would be 3.556 or 3.56
