Description
Sets the Intel FPU precision control mode.
This is an Intel platform dependent function.
This function is considered obsolete (Windows only, not cross-platform), and is not available for NEXTGEN compilers.
You can still change the precision mode by System.Set8087CW on Intel platform, but we do not recommend changing the FPU's precision mode programatically.
