How can PHP developers troubleshoot and resolve problems with decimal values not displaying correctly in output?

When decimal values are not displaying correctly in output, PHP developers can troubleshoot and resolve the issue by ensuring that the correct data type is used to store and manipulate decimal values. Using PHP's number_format() function can help format decimal values for display, and explicitly casting variables to float can ensure accurate calculations and output. 

// Example code snippet to fix decimal value display issue
$decimalValue = 10.555;
$formattedValue = number_format((float)$decimalValue, 2, '.', ''); // Format decimal value with 2 decimal places
echo $formattedValue; // Output: 10.56
