St1: d < 0.25 i.e h must be less than 5. So d will be 0.2: SUFF

Shouldn't h be < 4... If it is 0.246 --> 0.25 --> 0.3

But if it is 0.236 --> 0.24 --> 0.2

0.246 --> 0.25 --> 0.3 IS WRONG

0.246 --> 0.2 IS CORRECT

Rounding is not done right to left but its done left to right.

Taking this example: Round off 0.246 to nearest tenth

1. Look at the 100th digit.

a. If it is less than 5 then drop all other digits right to 10th digit and don't increase the tenth digit.

b. If it is greater than 5 then drop all other digits right to 10th digit and don't increase the tenth digit.

c. If it is equal to 5 then look the next digit right to 10th digit and again apply the same rules as in point a and b above.
