Kdyer Kdyer KiX Supporter Registered: 2001-01-03 Posts: 6241 Loc: Tigard, OR	Playing around with the following code and get two results. In Excel - 53 In KiXtart - 50 Here is the code: code: CLS BREAK ON ;Y0 + (X - X0) * (Y1 - Y0) / (X1 - X0) ; x y ;X0 1 35 ;X 4 ;X1 7 62 ;What is Y? $XO=1 $X=4 $X1=7 $Y0=35 $Y1=62 $INT=$Y0 + ($X - $X0) * ($Y1 - $Y0) / ($X1 - $X0) ?$INT GET $ I have added parenthesis too and it does not change the result. Thanks, Kent _________________________ Utilize these resources: UDFs (Full List) KiXtart FAQ & How to's
