Mathematica 6! as far as I know has the same Fault as all the other Versions!

it thinks Infinite/Recurring 0.9 equals 1

Re: Mathematica 6 Released

Ugh. Not this again.

Mathematica 6 thinks that 0.999... = 1 because it was programmed by some mathematicians, who also think that 0.999... = 1.
They think this because there are many proofs to support the statement and no contradictions that can't be shown to have flaws.

Now, this topic is meant to be for discussing Mathematica 6. If you want to bring up this debate again, please do so in the proper topic.

Why did the vector cross the road?
It wanted to be normal.

Re: Mathematica 6 Released

Well, mathematica has many other flaws beyond that. For example, after certain calculations of trig, it may give out a result like 3.6+0.000000000000001I. It may seem harmless so long that you know that it has applied sin to sinh, real to complex transformation, but it does cause trouble when ploting the function over more than one period. Besides, the Aspect Ratio thing and the Artificial Art-sense is handicapping, to think it cannot plot the whole curve up under real ratio just because the curve is tooooooooooooo flat ?!!

Re: Mathematica 6 Released

As I said before a Better Program would be an Unbiased program that just Calculates! according to the Question put to it! i.e to think in an Unbiased way!

Below is a program wrote in the Basic Computer Language! that does exactly what it is asked! i.e Calculate Infinite/Recurring 0.9 with no end! ever!................

10 N = 0.9
20 INPUT " PRESS ENTER " ; START
30 PRINT ; N
40 GOTO 10

Re: Mathematica 6 Released

That would print "0.90.90.90.9..." wouldn't it?

It depends on the version of "BASIC" used!! as is always the way with Computer languages!
some remove the Zero and keep repeating the .9 which is what it should do!
but I dont have a problem with any version printing  Infinite/Recurring 0.9 or .9 both have the same Value! the main point is that the Values printed are never ending!! i.e Infinite/Recurring!
The way you have showed it is wrong! "0.90.90.90.9..." with no Breaks! it should be .........

0.9
0.9
0.9

or

.9
.9
.9

Both are the Same!!

Re: Mathematica 6 Released

Below is my Infinite/Recurring 0.9 QBASIC Computer program!

To Run the program copy/paste and then save the file as INFREC09.BAS or INFREC09.TXT
then open the program in the QBASIC program's window to Run.

If you dont have a copy of the QBASIC program,it can be download for Free from
