Least lines possible!

Suppose you have to write a program which gives the quadrant of a certain point whose $x$ and $y$ coordinates are given using least lines possible

For python (you may use other programing languages too) , I made this function :

1	`def quadrant_of(x,y) : return 2.5 - y/abs(y) - 0.5 * xy/abs(xy)`

Now the next task is, to use least characters to form the program.

Can you do it?

Note :

Number of characters used in the names of variables or functions will be considered as a single character.
This program will work slow for large numbers (due to multiplication operation used in it), if someone can make it short and faster it will be appreciated too.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Woah! I really can't think of a different algorithm to do this, but I may have found a few tweaks to lower the character count:

1	`quadrant_of = lambda x, y : 2.5 - y/abs(y) - xy/abs(2x*y)`

#That's Good :) , just write
quadrant_of =lambda x, y : 2.5 - y/abs(y) - x*y/abs(2*x*y)#instead of 
quadrant_of_ =lambda x, y : 2.5 - y/abs(y) - x*y/abs(2*x*y)

Umm... suppose you change xy/abs(xy) into x/abs(x) * y/abs(y) ,it would have less time complexity, right?

Here the challenge is the number of lines. But remember if x, y is very large the multiplication might take some time, in this case, it is better to use if-else conditions.
