I would like to append this to what may be a record number of incorrect scripts
on my part. Hugh pointed out in the forums that the floor of 5 is 5, and the
ceiling of -5 is -5. These scripts might actually be correct, but I'm not
guaranteeing anything at this point... My apologies for the noise
My apologies... I tested this when I first wrote it, and I thought I had
everything covered. As others have pointed out, it requires a test for negative
integers, so it should be:
function Floor pValue
if pValue is an integer OR pValue < 0 then return trunc(pValue) - 1
else return trunc(pV
Beware:
This function fails when the number is a negative integer.

I’ve always thought that LC should include a roundUp and roundDown version of

Not to throw a wrench in the works, but wasn’t there some discussion in the
past about different versions of Julian dates? Which one is the more widely
accepted? I suppose the question could be formed, which one does Microsoft use
for Excel? :-)

Hey thanks for that Kay. I have a date conversion function that includes
formats like sqlDate which the LC covert command does not support. This will be
a nice addition.

Your function misses a special case. If the negative number is an integer, you
wouldn’t want to subtract 1 from trunc(theNegativeNumber).

Jacquie, I tested my script before I posted it, and it works for negative

Colin, just for fun, I've consolidated mine to one line.
Richmond, maybe you'd like to add "ceiling" to your sample stack?

Many languages equate booleans to 0 or 1. If LiveCode worked that way you could
say:
put trunk(n-(n<0))

Folks:
Try this:
You have to be sure that if myNum is a perfect negative integer, floor(myNum) =
myInteger
while
floor(-some non-integer) = trunc(myNum - 1)
Colin’s version works too.
on mouseUp
put 1.55 into tNum
put 1 into tCor

You could do it in one line:
put trunc(-14.2+10)-10
where the 10 part is a number bigger than anything you’re going to

Kay,
Thanks. I have been using Sarah Reichelt's Date & Time Library, which contains
these functions by Mark Wieder. I actually didn't realize they were under
copyright, but I see that now.
It says something nice about LC that this code is 10 years old and still valid
and valuable.

Nope, but this will help you calculate the Julian Date Number, which
you'll need:
put the date into tDate
convert tDate from date to dateItems
if ((item 2 of tDate = 1) or (item 2 of tDate = 2)) then
put 1 into tDay
else
put 0 into tDay
end if
put item 1 of tDate + 4
just for the
