to round to one decimal point all you have to do is move the decimal point once to the right for example: 0.808 becomes 08.08
2.4. If the second decimal is more than 5 then first decimal value would have become 5 ie one more. If it is less than 5 then the decimal value remains the same. This is our p…resent problem. Now question arises that what we have to do when the second decimal is exactly 5. It is a good question. When the second decimal value is 5 then look at the preceding value whether it is odd or even. If it is odd then change it to the next added by one. If it is even leave as it is. So interesting. Isn't?
0.827650000657 is one.
Splitting the number at 1 decimal gives 4.5 | 29 The digit after the "|" is less than 5 and so just ignore it all and the answer is 4.5
It then is: 326.6
It is 13.6 when rounded to 1 decimal place
It is 7.6
It is 18.9
It is 44.3
