_CIsqrt

  • 發行項

Calculates the square root of the top value in the stack.

void __cdecl _CIsqrt();

Remarks

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.
