Calculates the square root of the top value in the stack.
void __cdecl _CIsqrt();
This version of the
sqrt 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.
