Here's a quick routine to determine decimals WITH a value: ie: 1.234 goes out to 3 decimals, but doesn't account 2.000 for 3 decimal positions. Maybe this will work for your needs with some mods...

x = 1
? decpos( x )
x = 1.1
? decpos( x )
x = 1.12
? decpos( x )
x = 1.123
? decpos( x )
x = 1.1234
? decpos( x )
x = 1.12345
? decpos( x )
x = 1.123456
? decpos( x )


func decpos
lparameters lnX

lnI = 0
llMatch = .F.
do while NOT llMatch
	if ( lnX * ( 10 ^ lnI )) - int( lnX * (10 ^ lnI )) = 0
		llMatch = .T.
	else
		lnI = lnI + 1
	endif
enddo
return( lnI )
