PROGRAMMING:Angle with same end edge
If $$theta = 2K / PI + / alpha $$, then $$/ alpha $$and $$theta $$are angles with the same end edge. Please write a program to input the angle $$- theta $$, calculate and output the angle $$- alpha $$, which has the same symbol, absolute value less than $$2, and the same terminal edge.
####Input format
>$$\ theta $$(radian)
####Output format
>$$\ alpha $$(radians)
Requirements: output 6 decimal places
####Input sample 1
```in
-29.845130209103035765395
```
####Output sample 1
```out
-4.712389
```
####Input sample 2
```
twenty-seven point four eight eight nine three five seven one eight nine one zero six nine one
```
####Output sample 2
```
two point three five six one nine four
