Taco: Decimal-like Format from Integer

Given an integer n, your task is to extract the last three digits of its absolute value and format them into a decimal-like string representation. Specifically, let the last three digits (with leading zeros if necessary) be represented as an integer abc. You should output a string formatted as "a.bc", where a is the hundreds digit and bc are the tens and units digits, with bc always displayed as a two-digit number.

For example, if the last three digits are \(005\) then the answer is 0.05 and if they are \(123\) the answer is 1.23. Note that the sign of the input is ignored.

The mathematical operation can be described in \(\LaTeX\) as follows:

Given an integer \(n\), let \(d = |n| \bmod 1000\). Then, output the string representation of \(\left\lfloor \frac{d}{100} \right\rfloor\) concatenated with a decimal point and the two-digit representation of \(d \bmod 100\).

inputFormat

The input consists of a single integer \(n\) provided via standard input.

outputFormat

Output a single string representing the formatted number as described. The output should be printed to standard output.
