How can you use the `Math.round()` function in React.js to round a number to two decimal places?

This React.js code snippet demonstrates how to round a number to two decimal places using the Math.round() method. First, it multiplies the original number (5.6789) by 100 to shift the decimal two places to the right, making it an integer (567.89). Then, it applies Math.round() to round this integer to the nearest whole number (568). Finally, it divides the rounded integer by 100 to shift the decimal back two places to the left, resulting in the rounded number (5.68).
