3、gvoid__fastcallTForm1::Button1Click(TObject*Sender){   inti=123;   AnsiStringstr=IntToStr(i);} //AnsiString转double标准实用文案void__fastcallTForm1::Button1Click(TObject*Sender){   AnsiStringTest="123";   longdoubled=StrToFloat(Test);} //double转AnsiStringvoid__fastcallTForm1::Button1Click(TObject*Sender

4、){   doubled=123.456;   AnsiStringstr=FloatToStr(d);} //double转AnsiString并四舍五入void__fastcallTForm1::Button1Click(TObject*Sender){   longdoubled=123.456121212;   AnsiStringstr=FloatToStrF(d,ffFixed,5,4);//说明FloatTostrF里5代表从第几个数字的后一位开始四舍五入,4代表取4位小数。//执行后得到str是123.4600。:roll:   }//double转AnsiString使
