_CIatan

  • Article

Calculates the arctangent of the top value on the stack.

Syntax

void __cdecl _CIatan();

Remarks

This version of the atan function has a specialized calling convention that the compiler understands. It 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 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
