   ShowMessage('ShortNumberValue = '+FloatToStr(ShortNumberValue));
 end;

TRObject Syntax

 var
   LongNumberValue, ShortNumberValue : float;
 
 {
   LongNumberValue = 1234567890.123456789;
   ShortNumberValue = 123.12;
 
   ShowMessage('LongNumberValue = '+FloatToStr(LongNumberValue));
   ShowMessage('ShortNumberValue = '+FloatToStr(ShortNumberValue));
 }

Output:
