In what scenarios should PHP developers consider incorporating decimal values instead of float values for more precise calculations?

When dealing with financial calculations or any scenario where precision is crucial, PHP developers should consider using decimal values instead of float values. Float values can lead to rounding errors due to the way they are stored in memory, while decimal values provide more accurate results for calculations involving money or other precise measurements. 

$amount1 = '10.15';
$amount2 = '20.25';

$decimalAmount1 = new Decimal($amount1);
$decimalAmount2 = new Decimal($amount2);

$result = $decimalAmount1->add($decimalAmount2);

echo $result; // Output: 30.40
