Integer test for perfect square

Is there an integer test for a perfect square? Say I have a large
positive integer (1000 digits), and I want to know if it's a perfect
square, and I don't have floating point available. I ended up getting
around this by factoring the number, but I wonder if there's a quicker
way.
