急求啊
我想要让TSpinEdit的选项显示是有小数的，比如3.1415，求指导
[解决办法]

class PACKAGE TCSpinEdit : public TCustomEdit
{
private:
long FMinValue;
long FMaxValue;
TCanvas *FCanvas;
long FIncrement;
TCSpinButton *FButton;
bool FEditorEnabled;
int __fastcall GetMinHeight(void);
long __fastcall GetValue(void);
long __fastcall CheckValue(long NewValue);
void __fastcall SetValue(long NewValue);
void __fastcall SetEditRect(void);
