hello.

kingping does not want to discuss my bug report without some discussion on this list. i should have waited until mitch was around (i think).

anyways, i was discussing weird browser issues at the mozilla developer day. the only problem i have seen with ie and mozilla writing web pages differently is in how they make tables. ie needs more pixels for whatever reason. since a pixel is a pixel someone must have screwed up somewhere and started counting pixels with "1" instead of "0".

i was playing with the ifscompose plug-in and noticed a difference in the tutorial that owen wrote to go with the plugin: http://www.gtk.org/~otaylor/IfsCompose/ifs_tutorial/tutorial.html and the current plugin in which the first fractii now starts with 1 and not with 0 the way owen wrote it.

any discussion of this will be endured. thanks,

carol

The numbers in the IFS Compose plugin are used as so called ordinal numbers, i.e. they don't refer to a count of certain objects but to a order of the objects. As you can see at e.g. http://www.webster.com/mw/table/number.htm ordinal numbers start at 1 and there is no such thing as an ordinal number 0.

Hence the number "0" in the ancient version of the IFS Compose plugin was a bug and has been corrected for the Version 1.2.

Bye, Simon

1 is no ordinal number, you most likely mean "1st"?

Whether you assume 0 or 1 being the 1st natural number is only a matter of convention and convenience (depending on the subject matter). Most people start to count from 1, so it makes sense to use "1" as label for the 1st object, but it is nevertheless arbitrary, as one could for example also have used the labelling "a", "b", "c", ..., with "a" denoting the 1st object etc.

Hence the number "0" in the ancient version of the IFS Compose plugin was a bug and has been corrected for the Version 1.2.

One of the advantages of the current style is that the object with label "n" is the n-th object (I personally have no idea if the order of the objects actually matters in the case of IfsCompose, from what I see: if at all, not much). The previous mapping was not exactly a "bug", but less convenient with respect to this.
