对了，若要控制小数的精度，可以这样：
double a1 = 11.16789;
AnsiString a2 = FormatFloat("0.00",a1);
结果为：11.17

上面老兄看来是学CB的，pascal的形式应该是
function FloatToStrF(Value: Extended
Format: TFloatFormat
Precision,
Digits: Integer): string;
如aint := FloatToStr(afloat, ffFixed, 8, 3);

var
ff:double;
ss:string;
begin
ff:=12345.334556;
ss:=formatfloat(',##0.00',ff);
end;
ss值为：12,345.33
