A DESCRIPTION OF THE PROBLEM :

I would like to propose adding a simple round() method to Java, similar to Python's built-in round(). Currently, rounding to a specific decimal place in Java requires extra steps with Math.round() or BigDecimal, which can be verbose and less intuitive.

Proposed Solution:
A built-in round() method that rounds a floating-point number to a specified number of decimal places, as shown below:

Example Usage:
double result = round(3.14999, 2); // Returns 3.15
double result = round(123.4567, 1); // Returns 123.5

This would reduce verbosity and improve the developer experience.
