Ah! See it now. That *IS* weird. Looks like two additional spaces
indented in the first 8 numbers. Perhaps related to their length?
SET DECIMALS and SET FIXED are truly ancient xBase commands, and SET
commands in general -- either global in scope or scoped to a
datasession -- wreak all sorts of havoc with unintended side-effects.
It's a lot better to specify what you want in the actual command than
to depend on modifying the environment to suit program execution.
Try this:
FOR i = 1 TO 30
? ROUND((2^(1/6))^i,2) && compressed algorithm
NEXT
Fixed and decimals and printing to the screen are all pretty
old-school, but you're running BASIC here, and not really FoxPro.
It appears to be a bug. VFP seems to be calculating the output
length based on fixed being off, then printing the fixed on value in
that length right-justified.
Sincerely,
Gene Wirchenko
