Samples

Input #1

5.90

Output #1

5

We round down $5.90$ to an integer, $5$, and print it as an integer. Non-integer outputs such as `5.0` will be judged as incorrect.

Input #2

Output #2

0

There may be no decimal point in $X$.

Input #3

84939825309432908832902189.9092309409809091329

Output #3

84939825309432908832902189

Take care when handling large numbers.
