What are the recommended methods for converting numeric values to specific formats in PHP?

When working with numeric values in PHP, it's common to need to convert them to specific formats such as currency, percentages, or decimal places. PHP provides built-in functions and methods to easily achieve this. Some recommended methods for converting numeric values to specific formats in PHP include number_format() for formatting numbers with decimal points, sprintf() for formatting strings based on a format specifier, and round() for rounding numbers to a specific number of decimal places. 

// Convert a numeric value to a currency format
$number = 1234.56;
$currency = number_format($number, 2, '.', ',');
echo "$" . $currency; // Output: $1,234.56

// Convert a numeric value to a percentage format
$number = 0.75;
$percentage = number_format($number * 100, 2) . "%";
echo $percentage; // Output: 75.00%

// Round a numeric value to 2 decimal places
$number = 12.3456;
$rounded = round($number, 2);
