Why non-zero is true?

In programming and many mathematical contexts, non-zero values are often evaluated as "true" because they represent a condition or state that is active or affirmative. For example, in boolean logic, any number other than zero is interpreted as true, while zero is interpreted as false. This convention simplifies decision-making processes and control flows in algorithms and conditions. Thus, non-zero values effectively indicate the presence of something, while zero indicates absence.
