There are many ways to do it:

1) By using FloatToStr
   The string representaion keeps the same number of decimal place as the original number

Ex.:   Str := FloatToStr(MyRealNumber);

2) By using Format
   You can specify how the final string will look like

Ex.: Str := Format('%.4f', [PI]);

{ Str evaluates to '3.1428' }

You can use:
function FloatToStrF(Value: Extended; Format: TFloatFormat; Precision,
  Digits: Integer): string;

Ex:
DesireString := FloatToStrF(YourValue,ffFixed,7,4);
