>> From: Vincent Lefevre "vincent"
I'm searching for a way to obtain guaranteed multiple-precision
results with Maple.
A solution is true interval arithmetic. I used to use the intpak
package, but
* it has been said that the authors made wrong assumptions on the
accuracy of Maple functions (I could then use intpakX though,
but is it really reliable or does it also make assumptions based
on unknown facts?);
* intpak seems to be written for Maple 5, and Maple 5 doesn't run
on the most recent Linux machines. The intpakX package would be
affected by the same problem, as it is an intpak extension and
needs the intpak package.
Is there a working interval arithmetic package (and reliable enough)
for Maple 8?
Is the accuracy of Maple functions known? Note that when I say
"known", I want something that could be regarded as guaranteed,
based on proofs. Having guaranteed results for particular cases
such as sin(x) where x is close to a multiple of pi is important.
Thanks in advance,
Vincent Lefhvre.
