I have done a basic arithmetic calculation and got the answer aaHere is the SmallTalk code in Squeak: Transcript show: 'aa='.Transcript show: 23124234 * 431213; cr. The output is aa=99714703158429971470315842 is a decimal number.What can I do to display a number in any hex I want ??

You can discover such functions by giving an example in Method Finder. For instance 23 is represented as 16r17 in hex, so:
23 . '16r17'
will reveal the method. For any radix, see printStringBase: method.

Hello, thanks for your answer.
Here is my thinking:
Transcript show: (23124234 * 431213) hex; cr
The above code only displays a decimal in hexadecimal which is base-16. Now I want a decimal number to be displayed in base-17 or 20 or 100 or 250 or any positive integer. How can I do that? Is that possible in Smalltalk?
I tried "Method Finder" and typed in Selector Browser "23 . '17r16' , only to get the warning: no single method does that function.
Any method I can solve this problem ?

Yes, with printStringBase: method
Transcript show: ((23124234 * 431213) printStringBase: 17); cr

Thanks. That is what I want.
But when I type:
Transcript show: ((2423460) printStringBase: 250); cr.
A "MessageNotUnderstood" window pops up.
Is there a maximal base for displaying numbers?

Yes, the maximum base is 36, because we only use 0-9 and A-Z as digits:
$Z digitValue => 35
For larger bases you would have to invent your own digits.
Even digits beyond F (hexadecimal 15) are non-standard, and are allowed more as a syntactic curiosity than as something with a real application.
The only somewhat commonly used bases are 2, 8, 10, 13, and 16, as far as I know.

Hi.
I haven't run across a reason to use base 13. What domain was that in? Just curious, cbc

The answer is 42.

And Adams swears this was never planned. Pure co-incidence that it worked out that way. Hmmmmmm.....? cheers -ben

Yep. For those not yet in on the joke:
In Douglas Adams "Hitchhiker" trilogy the number 42 plays an important role, and at some point it was defined as 6x9. Intended as a joke, it turned out that this is actually correct in base 13, and can be written easily in Smalltalk, but not most other computer languages:
13r6 * 13r9 = 13r42 => true

Hi,
I get the feeling you are asking the wrong question. Can you tell us more about what you are trying to do.
