The C99 standard includes new real floating-point types float_t and double_t, defined in <math.h>. They correspond to the types used for the intermediate results of floating-point expressions when FLT_EVAL_METHOD is 0, 1, or 2. These types may be wider than long double. C99 also added complex types: float _Complex, double _Complex, long double ...
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.

Microsoft Visual C++ (MSVC) is a compiler for the C, C++, C++/CLI and C++/CX programming languages by Microsoft. MSVC is proprietary software ; it was originally a standalone product but later became a part of Visual Studio and made available in both trialware and freeware forms.
In computer science, boxing (a.k.a. wrapping) is the transformation of placing a primitive type within an object so that the value can be used as a reference. Unboxing is the reverse transformation of extracting the primitive value from its wrapper object. Autoboxing is the term for automatically applying boxing and/or unboxing transformations ...
Borland C++ was a C and C++ IDE (integrated development environment) released by Borland for MS-DOS and Microsoft Windows. It was the successor to Turbo C++ and included a better debugger, the Turbo Debugger , which was written in protected mode DOS.
Perhaps the most well-known example is C++, an object-oriented extension of the C programming language. Due to the design requirements to add the object-oriented paradigm on to an existing procedural language, message passing in C++ has some unique capabilities and terminologies. For example, in C++ a method is known as a member function.
A computer program written in an imperative language. Imperative languages specify a sequential algorithm using declarations, expressions, and statements: [52] A declaration introduces a variable name to the computer program and assigns it to a datatype [53] – for example: var x: integer; An expression yields a value – for example: 2 + 2 ...
