1. printf()
Hi,
I just detected that
printf(1, "%d\n", {1e254})
prints 255 '*'s. I wonder, whether this is intended.
Best regards,
Juergen

On Linux, it prints:

Sorry, I forgot to mention, that I got that result on Windows 98, using
the Eu 2.4 Beta interpreter.

No, it wasn't intended. I'll make a note of it. Thanks.
Euphoria's printf() does a bit of pre-processing before
calling C's printf(). The asterisks were generated by
Watcom C, used to build the DOS and WIN interpreters.
On Linux, GCC gives a better result
(accurate to about 16 decimal places.)
