I'm curious is there really a real-life use-case for the group spec ?
i.e. variable size groupings of digits ?
Not sure what order you want for currency and neg sign ? Should it be
$-123 or -$123
and should it be 123-$ or 123$- ?
Should there always be a 0 before the "point" ? i.e. could the result
be .12 rather than 0.12 ?
How about -.12 rather than -0.12 ?
Thanks for a fun challenge ....

OK, here's an amusing exercise in scripting for you experts out there, but I'm giving
away a prize! I will give the person who provides the best solution a copy of my band's
latest CD, Aged 10 years. the definition of "best" is strictly my opinion! If
you don;t like traditional Celtic music (including bagpipes), we;ll just do the script
for the fun of it and sell the CD on eBay!!!
You have an integer value that needs to be formatted into a currency value. It
is stored as a positive or negative binary value no matter how many decimal
places it has (eg 10000 = $100.00). You have the following formatting
characters to deal with:
currency symbol: always present
currency symbol position: 1 = before the number, 0=after the number
decimal delimiter : could be empty
number of decimals: could be zero and will be if decimal point char is empty
negative sign character: always present
negative sign position: 1= at the start of the formatted number , 0= at the end
of the formatted number
group separator character: Specifies the character separator used for grouping
digits to the left of the decimal delimiter in formatted monetary quantities.
Could be present even if no decimal delimiter is specified. Also could be
empty, meaning no grouping.
grouping spec: Specifies a string that defines the size of each group of
digits in formatted monetary quantities. Only present if the group separator is
not empty. Consists of a sequence of semicolon-separated integers. Each integer
specifies the number of digits in a group. The initial integer defines the size
of the group immediately to the left of the decimal delimiter. The following
integers define succeeding groups to the left of the previous group. If the
last integer is not -1, the size of the previous group (if any) is repeatedly
used for the remainder of the digits. If the last integer is -1, no further
grouping is performed.
Deadline is midnight Friday March 4th, California time. Good luck!
