 This header file declares some functions to produce a generalized Fibonacci sequence, given two initial values. A call to `fibonacci_init(1, 1)` generates the familiar Fibonacci number sequence.

-When the **MATHLIBRARY&#95;EXPORTS** macro is defined, the **MATHLIBRARY&#95;API** macro sets the `__declspec(dllexport)` modifier on the function declarations. This modifier tells the compiler and linker to export a function or variable from the DLL for use by other applications. When **MATHLIBRARY&#95;EXPORTS** is undefined, for example, when the header file is included by a client application, **MATHLIBRARY&#95;API** applies the `__declspec(dllimport)` modifier to the declarations. This modifier optimizes the import of the function or variable in an application. For more information, see [dllexport, dllimport](../cpp/dllexport-dllimport.md).
