What is the recommendation for using a Compute (CPT) instruction instead of standard arithmetic instructions like ADD, MUL, DIV or SUB?

The recommendation for using the Compute (CPT) instruction instead of standard arithmetic instructions like ADD, MUL, DIV, or SUB is often to avoid it in favor of more straightforward and traditionally accepted arithmetic operations. The CPT instruction is typically used for more complex expressions or when performing operations that require multiple calculations to be executed in a single instruction.

One of the main reasons for this caution is that standard arithmetic instructions are generally more efficient and easier to read and understand. Using explicit arithmetic instructions can improve the clarity of the code and enhance maintenance since most programmers are familiar with basic operations. Also, standard arithmetic instructions often leverage the processor's optimized handling of these operations, leading to better performance.

When considering programming best practices, clarity, and maintainability are crucial. The potential complexity introduced by the CPT instruction might make the code less intuitive, especially for teams or future developers who might work on the program. Hence, opting for straightforward arithmetic instructions is usually favored for most programming scenarios, making it advisable to avoid relying on the CPT instruction unnecessarily.
