in reply to Find range in array with indices

Agree with jdporter above, not aware of any coordinate system where 7.133 > 7.23.

I think maybe the varying degrees of accuracy are causing confusion? 7.133 is accurate to the thousandths place, where 7.23 is only accurate to the hundredths place. Does this make it easier to understand:

7.23 = 7.230

7.230 > 7.133

UPDATE:A-ha, so this isn't coordinate space, rather Tk indices, see Re: Find range in coordinates array below.

    what if it were 7-23 and 7-133 where each size of the - was its own integer co-ord, and 7.23 was actualy 7.0023 and 7.133 was 7.0133

    Quick untested idea for fix 

    sub fixit { 
my $pt=shift; 
  my ($x1,$x2)=split(/\./,$pt); 
  return sprintf ('%08i.%08i',$x1,$x2); 
}
....
last if (fixit($cursorPosition) <= fixit($tagBegin));

    Much optimzation could be done to that, but it gives you the idea

      Thank you. I played a bit with your idea (your assumption was right) and I managed to get a working solution. However, I finally used the solution proposed by Haukex because it seems... simply perfect.
