If you have a number say 1.x5 - if x is odd then it will be 1.(x+1)
-if x is even then it will be 1.x
Example :
1.35 will be rounded to 1.4 and 1.25 will be 1.2
-if x is even then it will be 1.x
Example :
1.35 will be rounded to 1.4 and 1.25 will be 1.2

While rounding off, all that matters is the number to the right. So assuming that you have to round off this number at the tenths place, check the number in the hundredths place. If that number is greater than 5, increment the number to the left, and if not then keep it as it is.
For example, if you have to round off 1.3478 to the thousandths place, check out the number to its right. Here the number is 8 i.e. greater than 5 hence we round up. Hence the answer becomes 1.348.
