Calculates the arctangent of x / y where x and y are values on the top of the stack.
Remarks
This version of the atan2 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.
Platform: x86
Alphabetical function reference
atan, atanf, atanl, atan2, atan2f, atan2l
