WebJan 5, 2013 · Since a perfect square that can be represented exactly in floating-point is an integer and its square root is an integer that can be precisely represented, the square root of a perfect square should always be exactly correct. Of course, there's no guarantee that your code will execute with a conforming IEEE floating-point library. WebSep 25, 2024 · Since the quadratic is a perfect square, this tells you that a root of that quadratic will have multiplicity 2 - you took a linear equation and squared it. If the quadratic vanishes at x = t, then so does this linear equation, but we have that linear equation twice by squaring, hence the multiplicity. So, we can deduce that the discriminant is 0.
