What is the difference between the division operator "/" and the bcdiv function in PHP?

When performing division in PHP, the division operator "/" can sometimes lead to precision issues due to the way floating-point numbers are stored. To ensure accurate division with arbitrary precision, the bcdiv function should be used instead. This function allows for precise decimal calculations by working with strings. 

// Using the division operator
$divisionResult = 1 / 3;
echo $divisionResult; // Outputs: 0.33333333333333

// Using the bcdiv function for precise division
$bcdivResult = bcdiv('1', '3', 2);
echo $bcdivResult; // Outputs: 0.33
