How do I calculate the length of hypotenuse?

Hypot is a mathematical function defined to calculate the length of the hypotenuse of a right-angle triangle. It was designed to avoid errors arising due to limited precision calculations performed on computers.

The Math.hypot(double x, double y) return the sqrt(x2 + y2) without intermediate overflow or underflow. The result will be same with this calculation
Math.sqrt(Math.pow(x, 2) + Math.pow(y, 2)).

How do I calculate exponential function?

In mathematics, the exponential function is the function ex, where e is the number (approximately 2.718281828) such that the function ex equals its own derivative. The function f(x) = ex at the point x = 0 is equal to 1.

How do I get the exponent of exponential function?

The exponential function is f(x) = ex. The Math.getExponent() method is used to get the x value of the given parameter, in which the parameter is a result of exponential function calculation.
