What is a numerical number?
1. Numeric is anything of, relating to, or containing numbers. The numbering system consists of ten different digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. If a value is an alphanumeric, it contains letters and numbers.
What is an example of numeric?
Numerical digits are the number text characters used to show numerals. For example, the numeral “56” has two digits: 5 and 6. The numeral “56” means: 6*10^0 + 5*10^1 = 6*1 + 5*10 = 6 + 50.

How are numeric data types defined in SQL?
In SQL, numbers are defined as either exact or approximate. The exact numeric data types are SMALLINT, INTEGER, BIGINT, NUMERIC (p,s), and DECIMAL (p,s). Exact SQL numeric data type means that the value is stored as a literal representation of the number’s value.
Can a numerical data be estimated and enumerated?
Estimation & Enumeration: Numerical data can both be estimated an enumerated. In a case whereby the numerical data is precise, it may be enumerated. However, if it is not precise, the data is estimated. When computing the CGPA of a student, for instance, a 4.495623 CGPA is rounded up to 4.50.
