1. error?
Ok, if
decimalcount = 1
(the debug screen says it is 1)
then shouldn't this line crash?:
resultnum = resultnum[1..decimalcount-1] & "." &
resultnum[decimalcount..length(resultnum)]
since it is the same as:
resultnum[1..0]
?

Actuall no, in Euphoria this is a perfectly valid statement. The docs are a wee
bit hard to understand on this point, but it works out like this:
slice[ # .. (anything greater than #) ] = a sequence
slice[ # .. # ] = a sequence length 1
slice[ # .. #-1 ] = a sequence length 0
slice[ # .. (anything less than #-1) ] = error
Ok, if
decimalcount = 1
(the debug screen says it is 1)
then shouldn't this line crash?:
resultnum = resultnum[1..decimalcount-1] & "." &
resultnum[decimalcount..length(resultnum)]
since it is the same as:
resultnum[1..0]

See refman_2.htm, 2.2.6 'Slicing of Sequences':
"x[3..2] is also allowed. It evaluates to the length-0 sequence {}."

No.
resultnum[1..0] is the empty sequence {}
resultnum = resultnum[1..decimalcount-1] & "." &
resultnum[decimalcount..length(resultnum)]
is the same as
resultnum = resultnum[1..0] & "." &
resultnum[1..length(resultnum)]

I can't help but consider that non-standard to Eu's way. It's one atom long, it
should be one atom returned. Or since Rob doesn't want to return reversed
sequences if we do
s = s[length(s)..1]
then s[1..0] should crash as a reversed sequence of as a "upper index is
less than 1" error. Reliable crashing is as important as reliable non-crashing,
isn't it?
