What are the drawbacks of using settype(), (double), or doubleval() for converting Oracle decimal values to PHP decimal values?

Using settype(), (double), or doubleval() for converting Oracle decimal values to PHP decimal values can lead to precision loss or incorrect rounding. To ensure accurate conversion, it is recommended to use the PHP function number_format() with the appropriate precision specified.

// Example code snippet to convert Oracle decimal value to PHP decimal value with precision
$oracleDecimal = 123.456789; // Oracle decimal value
$phpDecimal = number_format($oracleDecimal, 6); // Convert with precision of 6 decimal places
echo $phpDecimal; // Output: 123.456789
