The problem with the decimals is that you've declared all of your variables as integers and integers can't hold decimals. Try declaring x, y, d as doubles or floats.

I'm also suspicious of this line:

d = (b*b-4*a*c)^(1/2);

d = (b*b-4*a*c)^(1/2);

^ is the bitwise XOR operator and I think (1 / 2) is going to be 0 due to integer division.
