Which data type is the only one that can be used in calculations?
Boolean
That will vary on the programming language used, but in general, it is a data type with a fixed number of decimal digits - usually four - which internally stores the number it represented as a whole number - for four digits, that would mean multiplying it by 10,000. It is commonly used to store currency values, but it can also be used for other type of data, when you are sure you won't need more than four decimals; its benefit is that additions and subtractions with this data type are exact - they don't suffer from rounding errors that appear when converting between decimal and binary, with other data types.
There is no such data type. However, when we use user-defined data types of our own type, then that type of data can be stored in a variable. So as a term, you may say that user-defined data type can store any data. As the data-type used in any variable will be depending upon us.
Data structures are a way of storing and organizing data on a computer so that it can be used in a way that is most efficient and uses least resources. Algorithms are step by step processes for calculations which are used for data structures.
The data type of the Variable determines/indicates the type of data that can be stored in a field/variable
True.
In database systems, the fields Integer, Number, Floating, Long are the datatypes used for storing and representing numbers or numeric data. Calculations can be performed based on these data types. Refer to the application/system specific manual for the exact implementation of the above.
The data type of a field specifies the kind of data it can contain, such as text, numbers, dates, etc. It determines how the field is stored and how operations can be performed on it, like arithmetic calculations and comparisons. The field is used by storing and retrieving data according to its specified data type.
No
FALSE
In a spreadsheet the data is the actual values that you type in, that are then used in calculations. So if you were to type in a list of 10 numbers and then type a formula to add the ten numbers, it is the ten numbers that are your data. The formula is using your data. You could have other formulas that work on those 10 numbers, like getting the average or the highest or lowest number in the list. None of those formulas are your data though, just the original 10 numbers. You could then type in other numbers or dates or text and they would all form part of your data. But any calculations you do or formulas you use are not data.
Scientists can evaluate the mathematical calculations of others.
Databases are used to hold many kinds of data. You could not say that Access, or any other database, is best at handling any particular one. Commonly, text data is a regular data type used, such as in details about people. If you are doing a lot of calculations a spreadsheet may sometimes be better than a database for numbers, but a database can do lots of calculations too. Databases can store dates, logical values (Yes/No), pictures and so on. A database such as Access is designed to deal with data, so it is often what you want to do with that data that may influence how you store and process it and what application to use, rather than the data type itself.
Data Type : - It is used to identify the type of data. 'C' Language has a large no of data type, Thus it is also known by rich data type language: Data type are generally classified in three group: 1: Fundamental data type 2 Derived Data Type : 3 Use defined data type; 1 Fundamental data type: Fundamental data type includes i) The int data type: The data type int can store integer value only for eg. 14, 45, 78 declaration: int a,b; here we can store any value in variable a & b. ii) Char Data Type : The data type char can store character value only which is enclosed with single quote for e.g. 'c' declaration : char x = 'c' iii) Float Data Type:
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.

Plato believed that the only tools needed for geometric calculations was a compass and a ruler. The type of compass being the type with a pencil attached to a pointing device.
