LEAF - Leaf
A leaf is inscribed in a square. Given the length of a side of the square. Find the area of the leaf.
A leaf is the intersection of two quarter circles drawn from two opposite ends of a square, with the radius being equal to the length of a side of the square.
Input
In the first line there will be an integer t (t ≤ 105) the number of testcases. Next t lines will contain a number a (0 ≤ a ≤ 106), the side length of the square.
Output
Print the area of the Leaf. Errors less than 10-6 will be ignored.
Example
Input: 2

2
Output: 0.5707963268

There is a very little tricky case... If you can't find it; you'll get RTE :P ... But If you can find this, don't post it here. :)

To this kind of problem, the author should use a (self-constructed) judge "Ignore absolute or relative errors less than 10^-9". |
