PUB decn...do you have it PhiPi?

Sorry to bother you Phil, but I can't locate your 13 Jul 2010 posting of this.

The cat walked across the keyboard while I was modifying some Spin located just below that PUB. Well her foot steps selected the latter half of the PUB and keyed in lots of jibberish. So I manually corrected, I thought, what got clobbered. Later I realized that 'decn' is clobbered and prints 4 or 5 digits even though say 3 are desired.

Is it possible you recall the forum thread on 13 Jul.? I can't locate it. Just a reference to the thread title will be sufficient. The cats sure can crreate problems with one's source; or chew cables, or my original PropPlug cable. yeah.gif Thanking you in advance

    Yep, that's it Phil. Many thanks. I had one line missing somehow.

    PawSense! How cute. Will look into it later.

    ElectricAye, why don't you like cats?

    I love cats. They make excellent pencil sharpeners!

    Mee-ouch! Not again! ElectricAye has made his feelings towards my species known before:

    @PhiPi,

    Your 'decn' has two lines with "digits < 0" in it. Why would it not be "digits > 0"? As in why display anything if it isn't 1 or more digits?

    I'm getting strange results and haven't been able to figure out where the problem is. I get 4 digits displayed (and entirely wrong values) when 3 are specified!!!

    Since decn had no comments I tried to add some, but didn't understand some of what was going on; sure, I could guess, but I've been wrong at least 'once' before. (The "ADD COMMENTS HERE" was a note to myself to try to understand and describe what's happening.)
    PUB decn(value, digits) | mindigits, val               ' from PhiPi 13 Jul.2010 on forum
'' Print a decimal number, right-justified in a field width given by digits.
  mindigits := ((value < 0) & 1) + 1                            ' ADD COMMENTS HERE
  if (value <> $8000_0000)
    val := || value
    repeat while (val /= 10)                            ' determine # digits
      mindigits++
  if (value < 0 and digits < 0)
    printStr(string("-"))                               ' if negatkve, print '-'
    value := ||value                                    ' make absolute value '||'
  repeat (||digits - mindigits) #> 0
    if (digits < 0) 
      printStr(string("0"))
    else
      printStr(string(" "))
  dec(value)                                              ' print the value in decimal format


    A few more moments of your time would be appreciated.

    You can specify padding with leading 0's instead of blanks by setting digits less than 0. The absolute value of digits is used to determine the field width. If the field required to hold the number (mindigits) is greater than the field width specified, the larger value will be used instead. If value is negative, a minus sign will be inserted just to the left of the leftmost printed digit.

    Ah, leading zeros. That I didn't expect. Guess if I'd entered some -n value for digits it would have shown itself.

    Thank you so much for the clarification.
