_CItan
Calculates the tangent of the top value on the floating-point stack.
Syntax
void __cdecl _CItan();
Remarks
This version of the tan function has a specialized calling convention that the compiler understands. The function speeds up the execution because it prevents copies from being generated and helps with register allocation.
The resulting value is pushed onto the top of the floating-point stack.
By default, this function's global state is scoped to the application. To change this behavior, see Global state in the CRT.
Requirements
Platform: x86
