I know this is more a question of language and philosophy than of theory, but I have not been able to find anything on this, and it's difficult to believe that the word does not exist.
The quality of a number to be even or odd is called parity. The quality of a number to be positive or negative is called sign. What is the term for the quality of a number to be prime or composite?
Best Answer
The quality of whether or not a number is prime is called primality.
A primality test will tell whether or not a number is prime.
