Don't forget us that use 1 234,56 SEK , so maybe the ideal situation is a
(built in) function that use the national settings of the OS !

Ämne: Re: [Oorexx-users] Formatting a decimal number?
DecimalFormat looks really excellent! Puts in commas and trailing zeros plus
lots more.
I did play around with format and several other string and parse functions, but
in the end built a little function that did what I wanted - but it's very
specific to my immediate needs.
What's the status of decimalFormat? Can I expect to see it rolled into ooRexx
at some time, or made generally available? I'd be nice to use it for the Guide.
The only thing I'd like to see added is an option to treat a number *as if* it
had two decimal places, so formatting "123456" produces "1,234.56" or
$1,234.56". The rationale for this is that money amounts are often stored in a
database as some number of cents. The only time they're expressed as dollars
and cents is when they're presented on some form of user interface
(screen/printout/etc.). So presenting 123456 cents as $1,234.56 needs the "."
to be inserted in the right place.
But then, of course, all that needs is for the cents to be divided by 100 (or a
"." inserted in the right place) before using DecimalFormat...

Hi Oliver,
There is the format method of the String class and a similar format() built in
function. I've never used them much and didn't find them too easy to use.
Once you understand them, they are probably easy.
In the incubator is an implementation of a decimal formatting class:
svn+ssh://miesf...@svn.code.sf.net/p/oorexx/code-0/incubator/decimalFormat
written by Lee. I've never tried that at all and don't know how easy it is to
use.

I want to format decimal numbers of between 3 and 9 digits so that they have
the following format:
x,xxx,xxx.xx
For example:
123 ==> 1.23
123456 ==> 1,234.56
123456789 ==> 1,234,567.89
etc.
I can do it with a little routine, but after some searching, I've failed to
find an easy way to do it using one of the many ooRexx formatting functions.
Is there an easy way?
