- Data type - Wikipedia
Data types are used within type systems, which offer various ways of defining, implementing, and using them In a type system, a data type represents a constraint placed upon the interpretation of data, describing representation, interpretation and structure of values or objects stored in computer memory
- Double-precision floating-point format - Wikipedia
Before the widespread adoption of IEEE 754-1985, the representation and properties of floating-point data types depended on the computer manufacturer and computer model, and upon decisions made by programming-language implementers E g , GW-BASIC 's double-precision data type was the 64-bit MBF floating-point format
- 64-bit computing - Wikipedia
The main disadvantage of 64-bit architectures is that, relative to 32-bit architectures, the same data occupies more space in memory (due to longer pointers and possibly other types, and alignment padding) This increases the memory requirements of a given process and can have implications for efficient processor cache use
- Category:Data types - Wikipedia
In computer programming, a type or data type is a defined kind of data, that is, a set of possible values and basic operations on those values This category contains articles and subcategories about data types generally and about specific, commonly-used data types
- Primitive data type - Wikipedia
Primitive data type In computer science, primitive data types are sets of basic data types from which all other data types are constructed [1] Specifically it often refers to the limited set of data representations in use by a particular processor, which all compiled programs must use
- Floating-point arithmetic - Wikipedia
The "decimal" data type of the C# and Python programming languages, and the decimal formats of the IEEE 754-2008 standard, are designed to avoid the problems of binary floating-point representations when applied to human-entered exact decimal values, and make the arithmetic always behave as expected when numbers are printed in decimal
- Value type and reference type - Wikipedia
Value type and reference type In certain computer programming languages, data types are classified as either value types or reference types, where reference types are always implicitly accessed via references, whereas value type variables directly contain the values themselves [1][2]
- Type conversion - Wikipedia
Type conversion In computer science, type conversion, [1][2] type casting, [1][3] type coercion, [3] and type juggling[4][5] are different ways of changing an expression from one data type to another An example would be the conversion of an integer value into a floating point value or its textual representation as a string, and vice versa
