This is a script that requires input from the command line (it's not a function). It's floating point accuracy (so no rounding).

Solution:

eval(-[5,-2:3,-3:2]+['nlouu*$$',39,']2/7'])

Explanation:

eval( <string> ) % Evaluated the string inside the brackets and executes it
Everything inside the eval call gets evaluated to input('')^2.5

How?

-[5,-2:3,-3:2] % A vector: [-5, 2, 1, 0, -1, -2, -3, 3, 2, 1, 0, -1, -2]
['nlouu**$$',39,']2/7'] % This is a string: nlouu**$ concatenated with the number
. % 39 (ASCII ']'), and ']2/7'. Thus, combined: 'nlouu**$$']2/7'

Adding the first vector to this string will convert it to the integer vector:
[105, 110, 112, 117, 116, 40, 39, 39, 41, 94, 50, 46, 53]

eval implicitly converts this to a string, and these numbers just so happens to be: input('')^2.5
