Quadrant

Language/Type: VB if/else function basics return

Write a function named Quadrant that takes as parameters a pair of real numbers representing an (x, y) point and that returns the Quadrant number for that point. Quadrants are numbered as integers from 1 to 4 with the upper-right Quadrant numbered 1 and the subsequent Quadrants numbered in a counter-clockwise fashion: 

                     ^ y-axis
                     |
                     |
                     |
         Quadrant 2  |  Quadrant 1
                     |
<--------------------+--------------------> x-axis
                     |
         Quadrant 3  |  Quadrant 4
                     |
                     |
                     |
                     V

Notice that the Quadrant is determined by whether the x and y coordinates are positive or negative numbers. If a point falls on the x-axis or the y-axis, return 0. Below are some sample calls.

Call Value Returned
Quadrant(12.4, 17.8) 1
Quadrant(-2.3, 3.5) 2
Quadrant(-15.2, -3.1) 3
Quadrant(4.5, -42.0) 4
Quadrant(0.0, 3.14) 0
