The latest version of this topic can be found at Data Type Ranges.Visual C++ 32-bit and 64-bit compilers recognize the types in the table later in this article.int (unsigned``int) __int8 (unsigned``__int8) __int16 (unsigned``__int16) __int32 (unsigned``__int32) __...
DWORD_PTR typedef ULONG_PTR DWORD_PTR; //Unsigned long type for pointer precision. Use when casting a pointer to a long type to perform pointer arithmetic. (Also commonly used for general 32-bit parameters that have been extended to 64 bits in 64-bit Windows. ) DWORD32 typedef unsigned in...
Float Data Type in C (With Example) The float data type allows programs to represent real numbers with decimals like 3.141592 in the program’s codebase instead of integers like 3 only. The float data type size is 4 bytes, i.e., it occupies 4 bytes of memory. It ranges between +/-...

Use Excel with your keyboard and a screen reader to name cells and data ranges in a worksheet. We have tested it with Narrator, JAWS, and NVDA, but it might work with other screen readers as long as they follow common accessibility standards and techniques. You...
This rule is useful when you need to preserve the precision of the result and are okay with losing range information, for example when adding values with meaningful precision, and whose ranges are significantly smaller than their data types can represent. The accumulator data type rule is set ...
ODBC C data types indicate the data type of C buffers used to store data in the application. All drivers must support all C data types. This is required because all drivers must support all C types to which SQL types that they support can be converted, and all drivers support at least ...
Stored bit type value. BIT(M) can store up to M bits of values, and M ranges from 1 to 64. B'1111100' B'1100' TINYINT BYTEA Time and date DATE The value is in the YYYY-MM-DD format and ranges from 1000-01-01 to 9999-12-31. For example, December 30, 1973 will be stored...
