The case 0^0 "Uncertainty" from book has nothing to do with engineering works.
Convince yoursef: e-323^0=1 ,,,, e-324^0="uncertainty".
The usable variables [x,t ,,,] can't be < e-15 because of the numerical
Windows approximations. So, when specifying t:=0,0.001..1
'0' in there is e-15. That some work sheets can be rescued this way is
just a band aid not presentable to Engineering/Scientific Community,
neither for publishing, 5346 didn't suffer this bug.

The other bug is about the binary '1' unproperly uncoded as well as the
binary '0'.

Another bug has been found: 6179 can't calculate bracketed exponentiation.
Neither on Win 7 and XP Pro.
(-467.5)^1.7="can't calculate"
-467.5^1.7=result

6179 freaks XP Pro the X_Y plot, can start plotting ln(x) only from 1 !!!
6179 looks compatible with Win 7.

...more bugs:

1. bracketed bug confirmed Win 10 (-467.5)^1.7="Index was outside of the bounds of the array".
No idea what that means ! ?

2. Vectorise [attached] takes only a local expanded matrix:
rejects from calculated in work sheet,
rejects from file read,
rejects from 'submatrix'

Lovely matrix shrink/expand but found no way to select the all matrix except if
fully expanded. Think in term of large size matrix. So, for large or small size matrix
one must fully expand/copy/paste in new assigned matrix for the vectorise.

Observe 6179: Min(,) => min(,) ... Max(,) => max(,)

More bug to come wrt "Conjugate Gradient" Genfit

Hope it will help fix 6179.

Cheers, Jean

"can't calculate" is a bug in the numeric engine (negative base with decimal exponentiation; the case is not managed and this triggers the final "index out of range" cryptic error); symbolic engine works correctly


Second is calculated because it is -(467.5^1.7) (you can notice it only if you select the math object on the canvas)



Other yet to investigate.

P.S. in future please try to keep each bug in a separate topic, it makes easier to investigate/discuss/keep track of them.
