Re: Formatting a number with two or more decimal points

[Bob Sneidar]

A number with more than one period... is not a number. An IP address is not a 
number. It's a period delimited list of decimal values ranging from 0 to 255. 
It may help to think of them as such.

Re: Formatting a number with two or more decimal points

You could just use the replace function.

function newnum pnum
   put offset(".",pnum,3) into trem
   if trem = 0 then --only a single decimal
  return pnum
   else
  --we have more than on decimal, remove good number for later
  put char 1 to trem+2 of pnum into newnum
  delete char 1 to trem+2 of pnum
  --fix remaining numbers
  replace "." with " 0." in pnum
  --return the lot
  return newnum 
  end if
end newnum

This assumes the numbers to unpack are less than 100 (i.e. 99.99 is the 
largest).

If not, you would need to adjust the initial conditional to work out if there 
was a compaction.

  Great! Many Thanks to Matt and James for posting this code :D
I found an example of 13 numbers in a single word within a svg file.

I have already included Matt's handler in the stack
SVGL_2015_rev01 posted within this thread in the forums:

http://forums.livecode.com/viewtopic.php?f=10=25612=134343#p134309

Later today, I will test James handler.

After completed all revisions, I will include links to your messages in the
mail list or forum to acknowledge your contributions.

Many Thanks for your help to update this stack!

Formatting a number with two or more decimal points

[Alejandro Tejada]

Hi All,

Recently, while updating Ian's SVGL
to import some SVG archives that
you could download from OpenClipart.org
I found an error processing this number:
80.26.12

This looks like a number with two decimal points
but it's a shorthand for two numbers that some
SVG editors use to save space by replacing two numbers
like 80.26 0.12 with a single word like this: 80.26.12
Notice that two characters: " 0" (a space and
number zero) are missing.

Quickly, I scripted a workaround like this:

Function ConvertWordtoNumbers pWordN

put pWordN into tWordNumber -- pWordN contains "80.26.12"

if "." is in tWordNumber
then

replace "." with cr in tWordNumber
if the number of lines of tWordNumber = 3
then
return line 1 of tWordNumber & "." & line 2 of tWordNumber && "0." & line 3
of tWordNumber
else return pWordN -- unchanged word or unchanged number
end if

else
return pWordN
end if

end ConvertWordtoNumbers

My question is:
How could you rewrite this code
to make it more elegant, faster,
efficient and cover an extreme
case like this:
10.26.12.47.38.52.71
(6 numbers in a single word)
10.26 0.12 0.47 0.38 0.52 0.71

Autotracing applications could produce
curves as unusual as these.

Thanks in advance!

Re: Formatting a number with two or more decimal points

[Matt Maier]

This works with the two cases you described. I've heard that "repeat while"
isn't the fastest option, but it sounded like 6 repeats would be an extreme
case, so it probably doesn't matter.

on testingTesting
   -- 10.26.12.47.38.52.71
   -- 10.26 0.12 0.47 0.38 0.52 0.71
   --   put "80.26.12" into tBlerg
   --   put "10.26.12.47.38.52.71" into tBlerg
   put "10.26" into tBlerg
   put convertWordToNumbers(tBlerg) into tBlergBlerg
end testingTesting

function convertWordToNumbers pWordN
   put pWordN into tWord
   split tWord by "."
   if the number of lines of the keys of tWord > 2 then
  put tWord[1] & "." & tWord[2] into tAll
  put 3 into tCounter
  repeat while tCounter <= the number of lines of the keys of tWord
 put " 0."& tWord[tCounter] after tAll
 put tCounter + 1 into tCounter
  end repeat
  return tAll
   end if
   return pWordN
end convertWordToNumbers
