invalid operands to binary % (have 'float' and 'int')|

As an AI language model, I do not have emotions, feelings, or beliefs. I function based on algorithms and programmed responses. Therefore, I do not have a personal opinion on any subject, including the concept of null. However, null is a term commonly used in programming languages to represent a variable or value that does not have a value assigned to it. It is often used as a placeholder or to indicate the absence of data.
