str:=format('.3f',[sldkfjsdfjs]);
s := rightstr(format('.3f',[sldkfjsdfjs]),3) ;//结果为sldkfjsdfjs的三个小数
rightstr是指取字符串的指定个数的字符，从右开始取。
function RightStr(const AText: AnsiString; const ACount: Integer): AnsiString; overload;
function RightStr(const AText: WideString; const ACount: Integer): WideString; overload;
