Using Number Variables
The Math Library

For more complex mathematical calculations, we can reference the Math library which is inherited from Java. It consists of various mathematical functionalities that cover a range of topics from logarithms, trigonometry, statistics, and more. Let’s take a look at some of the most commonly used functions it provides.

Math.pow() returns the first value raised to the power of the second value. It accepts and returns Double values.

Math.pow(5.0, 3.0) // 125.0

Math.min() returns the minimum value from two given numbers.

Math.min(5, 3) // 3

Alternatively, Math.max() determines the maximum value.

Math.random() returns a randomly generated number between 0 and 1.

Math.random() // 0.3335735290527727

Math.round() accepts a single Double value and returns the result of rounding that value to the nearest Integer.

Math.round(15.7) // 16
