Line 1: ==More special cases== There may be more special cases. If p1==p2 and r==0, there is one unique answere that's a zero radius circle. If ~~tow~~two points are separated by exactly double the radius, there's only one answer. The latter can be treated as two identical circles, but then so can the former. <lang python>from math import sqrt Line 35: == XPL0 == REXX referred to XPL0. This ~~secion~~section was removed at some point in time. ~~Unfortuately~~Unfortunately the ~~Histore~~History does not show when and by whom. I restored now the old section --Walter Pachl 08:35, 15 October 2017 (UTC) : By   ''referred to'',   it was meant that REXX entry was a translation   <nowiki> {{trans\|XPL0}} </nowiki>   of the   '''XPL0'''.   entry.   -- [[User:Gerard Schildberger\|Gerard Schildberger]] ([[User talk:Gerard Schildberger\|talk]]) 08:43, 15 October 2017 (UTC) :: What's that other than a reference? --Walter Pachl 08:52, 15 October 2017 (UTC) ::: A reference could be anything that referenced (mentioned) something else by name but not necessarily contained herein on Rosetta Code   --- for instance, the language   '''xyz'''   used/uses the assumption(s) yadda-yadda-yadda,   or entry   '''xyz'''   used a similar approach, logic, data (for input), ...   or any other number of things, most often (but not limited to) somewhere in the entry's preamble (or comments made elsewhere).   However, a   <nowiki> {{trans\|XPL0}} </nowiki>   means that (in this case) the   '''REXX'''   entry used (most likely) the   '''XPL0'''   entry (the source code here on this Rosetta Code task) as a basis or prototype for the computer programming language translation.   -- [[User:Gerard Schildberger\|Gerard Schildberger]] ([[User talk:Gerard Schildberger\|talk]]) 09:52, 15 October 2017 (UTC) :Walter, the XPL0 was actually never ''removed'': [http://rosettacode.org/mw/index.php?title=Circles_of_given_radius_through_two_points&diff=209250&oldid=208439 this edit] adding the entry on Visual FoxPro mistakenly ended with a ''pre'' HTML tag, which made the XPL0 entry show up at the end of the VisualFox Pro entry. I'll remove it now. [[User:Eoraptor\|Eoraptor]] ([[User talk:Eoraptor\|talk]]) 20:17, 28 December 2017 (UTC)
