You relax and do nothing. The number is already rounded to 1 dp.
It depends how many decimal places or significant figures you are rounding to.Here's the general method for if you're rounding to 2 dp (decimal places);Look at the number in the 3rd dp spot. Is it 5 or above?If no, write the number with only 2 dp ignoring the 3rd dp number completely. If yes, you'll need to increase the number in the 2nd decimal place spot by 1, unless ...The 2nd dp number is a 9 (as it is in the above question). In that case you need to increase the 1st dp number by 1 and make the 9 a zero. Unless ...The 1st dp number is a 9 ..... etc. etc.So for our example;Rounding to;2 dp = 8.201 dp = 8.20 dp = 8
It is already rounded to 2 dp.
147 is already rounded to 0 decimal places. But if you mst try to round it to 1 dp, is should be written as 147.0
√245 ≈ 15.65Calculate to 3 dp and round using the 3rd dp:............ 1 . 5 . . 6 . 5 . 2 ⇒ √245 ≈ 15.65 to 2 dp............-----------------....... 1 | 2 45 . 00 00 00............ 1............ -..... 25 | 1 45............ 1 25............ -----... 306 | .. 20 . 00............... 18 . 36............... -------. 3125 | .... 1 . 64 00................. 1 . 56 25................. ---------31302 | ........... 7 75 00........................ 6 26 04........................ --------........................ 1 48 96

068 is an integer and already rounded to more than 1 dp.
There is no sensible meaning to "31 round to 1 dp" because the number is already rounded to a greater degree than that!
The 2nd decimal place is a 4, so round down: → 0.0471 to 1 dp is 0.0
1/3 = 1 ÷ 3 = 0.333... (with the 3 recurring). When rounding to any number of decimal places it will round down, so stop after as many 3s as decimal places to which you want to round. eg to 1 dp 1/3 ≈ 0.3 to 4 dp 1/3 ≈ 0.3333
1, 3, 9, 197, 591, 1773
To 4 DP, 62.1935 To 3 DP, 62.194 To 2 DP, 62.19 To 1 DP, 62.2

if the amount is in dollars, rounding to 2 dp: $1018.52 If the amount is in cents, rounding to 0 dp: ¢1019
It is already rounded to 2 dp.
