What is the function of the bcmul function in PHP?

The bcmul function in PHP is used for performing precise multiplication operations. It takes two parameters, which are the two numbers to be multiplied, whether they are integers or floating point numbers, and returns their product value.

In comparison to the regular multiplication operator (*), the bcmul function can be used for precise calculations on numbers of any length, avoiding the issue of precision loss when dealing with floating point numbers. This is particularly useful in handling financial data, scientific calculations, and applications requiring high precision calculations.
