I transferred both of my images ( 8 and 9) across and put them in the images
directory of a new Pharo Launcher. I now have 9.0 working on the Mac mini but
it is still telling me that my VM is out of date. I have opened the VM window
and updated both the 8 and 9 vm but I still get the message. I

Hi Esteban
Do you know when the fix for the extent problem under Gtk will be in the
image? I downloaded the latest Pharo 9 image a couple of days ago and,
though the fix was in for the extent problem in Morphic, it still didn't
work in Gtk.
Thanks.

Hi,
Yes, it is there.
Thing is... since cairo does not informs correctly extent of surface in x11,
what I did is to add an extra parameter to the drawing block, as you can see in
the example :
SpAthensPresenter>>#exampleResizing
| extent |
extent := 350@300.
self new
surfaceExtent: extent;
draw
boo... format lost :P

The problem is that while it is possible to read the ANSI Smalltalk
standard as requiring ScaledDecimals to be fixed point numbers (which are a
kind of exact rational number of the form x * 10**y, x and y integers), in
Squeak and Pharo ScaledDecimal numbers are NOT fixed-point numbers. They

I am also a bit intrigued by this. Like you said: several other programming
languages (I tried a couple of Common Lisp and Scheme implementations) do the
same as Pharo, but handheld calculators, normal and scientific, do not.
I think that going for 1/10 fractions/precision is not going to help:
Many thanks esteban - works fine now in Gtk

I am nearly there. I sorted out the curl/wget business and managed to get the

However there are two things I am not sure of.

I didn't know there were decimal floats.
Are they used elsewhere?

Hi Guys,
I'm posting from an http form and I'm wondering how to read data from the

Can you help me please?

2Decimal floats are (a) part of the IEEE 758-2008 standard for
floating-point arithmetic,
(b) implemented as part of the instruction set in IBM z/Series and
POWER computers,
(c) allowed for in the current C standard, (d) partially supported by GCC

First, I am not criticising YOU. Pharo's weird ScaledDecimal is

and you have not changed it. Fine.

True, but irrelevant.
