Hello guys

I made this function to get the percentual from two value, but sometimes it works fine and sometimes it doesn't.

could you help me to ajust it?

Thanks a lot

alter Function  fn_PercentualDesconto (@Fullvalue float, @EndValue float)
  Returns Float
Begin 
	declare @v01 float;
	declare @v02 float;
	declare @v03 float;

        Set @v01=@Fullvalue 
	Set @v02=@EndValue 
	Set @v03=(@v01-@v02)
	Return 100- round((@v03 / @v01 ) * 100 , 2) 
End
