The method below checks if 3 non-negative numbers form a Pythagorean Triple. This situation occurs when the sum of the squares of two of the first two numbers equals the square of the third. For what reason would the code sometimes incorrectly return false, when provided with 3 numbers that are actually a Pythagorean Triple?

public boolean isPythagTriple(double a, double b, double c)

{

double d = (a*a + b*b);

double e = (c*c);

return (d == e);

}
