Coordinates quadrant

Input coordinate values (x, y) in the plane rectangular coordinate system that determines the point at which the quadrant or which of the coordinate axes.
Specific requirements:

Output Quadrant integer: 2, 3 or 4; lowercase letters output axes: x or Y; if the coordinates on the origin, the output number zero: 0;
Test Example:
Test Input: 1.3 -2.0
Expected Output: 4
test input: 0 -2.3
expected output: Y
test input: 00
expected output: 0
