Well, not anymore.
Stop whimpering for 5 year old version of SMath. (v0.98.6179)
Guess what, this kind of bugs are being corrected.
AND NEW VERSIONS ARE RELEASED FOR THOSE CORRECTIONS.
There is no practice of releasing a new version with same version number.
You should just keep installing latest stable releases.

And it is obvious you function give an error.
That factorial is above max. number allowed.

It makes me want to write a book with the title...the strange art of giving difficult answers to questions that have never been asked

First he whine about a calculation of 5 year old version bug which is fixed.
And now he is complaining about SMath integration is not accurate.
Well, it is known by all of experienced users.

Maybe it is not a bug, more like a limitation.
SMath is using IEEE754 double, it won't accurately make this 334 decimals division.
If he want to integrate that accurate, than he should use maple or maxima.
By the way, I can get accurate more than 500 digit with same functions.
If he wants floating point, let me see if Jean can pass this.
And his function is wrong at 15th digit.

That's a Monk job !
By same token, Sine Integral has applications in
Process Control & Instrumentation [critical ramp set point].
Cheers ... Jean.

A much easier calculation that Jean can stop weeping.
Well, I doubt what I say.
