Hi Kirk,

with string use this :

CREATE CURSOR ctab (LayoutValue N(10,4))
SET TALK OFF
CLEAR

INSERT INTO ctab VALUES(4.1000)
INSERT INTO ctab VALUES(4.1100)
INSERT INTO ctab VALUES(4.1200)
INSERT INTO ctab VALUES(4.1110)
INSERT INTO ctab VALUES(4.2000)
INSERT INTO ctab VALUES(4.2100)
INSERT INTO ctab VALUES(5.0000)
INSERT INTO ctab VALUES(5.1111)
INSERT INTO ctab VALUES(5.2110)
	 
INDEX ON BINTOC(LayoutValue);
	+	CHR(LayoutValue*10000 	% 10);
	+	CHR(LayoutValue*1000 	% 10);
	+	CHR(LayoutValue*100	% 10);
	+	CHR(LayoutValue*10  	% 10) TAG LayOut1

BROWSE

SELECT *;
,	BINTOC(LayoutValue)				;
+	CHR(LayoutValue*10000 	% 10)	;
+	CHR(LayoutValue*1000 	% 10)	;
+	CHR(LayoutValue*100 	% 10)	;
+	CHR(LayoutValue*10  	% 10)	expSort;
	FROM ALIAS() ORDER BY  expSort

With pure math trasformation ( but VFP can insert rounding errors ):

INDEX ON	INT(LayoutValue			)*10000	;
+		INT(LayoutValue*10000	%10	)*1000	;
+		INT(LayoutValue*1000	%10	)*100	;
+		INT(LayoutValue*100	%10	)*10	;
+		INT(LayoutValue*10	%10	)		;
TAG LayOut1
