What does numeric mean in SQL?

Zero is neither positive nor negative and thus it is considered a neutral number. Mathematicians agree zero is a counting number, a whole number, and an integer.
What is the nature of the number 20?
The number 20 is a combination of the 2 and 0 vibrations. The 0 vibration makes the 2 vibration more complete, but it cannot change its nature.
Is the number 20 more related to 2 or 0?
The number 20 is a combination of the 2 and 0 vibrations. The 0 vibration makes the 2 vibration more complete, but it cannot change its nature. The number 20 reduces to the number 2, so the 20 is more related to the number 2 than the number 0.
