The char data type is a single 16-bit, unsigned Unicode character. It ranges from 0 to 65,535. They are not integral data type like int, short etc. i.e. the char data type can't hold the numeric values. The syntax of declaring a char type variable is shown as:char caps = 'c';
no
A primitive data type is built into the language - int, char, long, etc. A non-primitive data type is am abstract data type that is built out of primitive data types - linked list, queue, stack, etc.
For Microsoft SQL Server there are no numeric values that consume 3 bytes. The numeric data types, their value range, and byte consumption as we follows: Data type Range Storage bigint -2^63 (-9,223,372,036,854,775,808) to 2^63-1 (9,223,372,036,854,775,807) 8 Bytes int -2^31 (-2,147,483,648) to 2^31-1 (2,147,483,647) 4 Bytes smallint -2^15 (-32,768) to 2^15-1 (32,767) 2 Bytes tinyint 0 to 255 1 Byte
Numeric data refers to any data that is represented as numerical values, such as integers, decimals, or fractions. This type of data is used for quantitative analysis and calculations in various fields such as mathematics, statistics, and science. Numeric data can be manipulated and processed mathematically to uncover patterns, trends, and relationships within the data.
It is a numeric type of data, or it could be called a value.
type '=SUM(enter the numeric data here)'. for example if you have numbers listed in cells A1-A10, you would type =SUM(A1:A10)
Any type of analysis that deals with numeric data (numbers) is quantitative analysis. Qualitative analysis, on the other hand, does not have numeric data ( for example, classify people according to religion).
There are several different types of data. Some include qualitative and quantitative. Qualitative is data that is not numeric and quantitative data is numerical.
because once you learn to type numbers on the numeric keypad, you can type them much faster, good for people who have to do a lot of calculations on their computers. When the standard QWERTY keyboard was introduced there were "text" type applications and data type. The key pad was added for the speed of entering numeric data in to fields and cells as in the case of spreadsheets. The number keys across the keyboard above the qwerty were to slow for many data punchers so the numeric pad was added
If you will read typecasting on php, you will know more on this. <?php $str = "10"; $num = (int)$str; ?>

Data types supported by MySQL are date and time data, numeric data, and byte data. Spatial data is another type supported by MySQL which includes the use of spatial extensions.
C is statically typed. There is no need for dollar or percentage symbols to differentiate between character/string data and numeric data.
Numeric means a number is used. For a key, that would usually be an integer. Non-numeric keys can include any symbols (i.e., text). In theory, you could also use other specialized data types, for example, dates. Check the data types available by a specific RDBMS; details may vary. Almost any data type can be used for a key; although variable-length data types such as BLOB are either not supported or not practical to use.
