How does PHP handle the conversion of decimal numbers to binary numbers, and what potential pitfalls can arise from this?

PHP uses the `decbin()` function to convert decimal numbers to binary numbers. One potential pitfall is that this function only works with positive integers, so negative numbers or floating-point numbers will not be converted correctly.

$decimalNumber = 10;
$binaryNumber = decbin($decimalNumber);
echo "Decimal number: $decimalNumber\n";
echo "Binary number: $binaryNumber";
