Java Math Class Methods
- abs(): Computes the absolute value of a number, ensuring all results are non-negative.
- round(): Rounds a floating-point number to the nearest whole integer, using standard rounding rules.
- ceil(): Always rounds a number up to the nearest whole number, regardless of its decimal value.
- floor(): Always rounds a number down to the nearest whole number, effectively discarding the decimal part.
- max(x, y): Compares two values and returns the greater of the two, useful for finding maximum values.
- min(x, y): Compares two values and returns the smaller of the two, ideal for identifying minimum values.
- pow(x, y): Raises a number x to the power of y, allowing calculations of exponentiation.
- random(): Generates and returns a double value that falls within the range [0.0, 1.0), providing a basis for random number generation.
- sqrt(): Calculates and returns the square root of a given number, essential for various mathematical operations.
