What is the purpose of the php bcdiv function?

The bcdiv function in PHP is used to divide two numbers and return the result as a string. It can perform division with any level of precision, avoiding the precision loss issues that can occur with floating-point operations. The bcdiv function takes three parameters: the dividend, the divisor, and an optional decimal precision. The decimal precision parameter specifies the number of decimal places in the result, with a default value of 0.
