Hello Peng,
I have the same **bad** behaviour with results changing, in my worksheet
cell, after running and restarting the project ad libitum.
When coercing to RR
def mypsi(z):
return psi(RR(z)
i have other random values too.
I can't track down code, because python code includes 1/ automatic coercion
(to RR or CC) 2/ a wrapper to gynac/pynac...so maybe, deeply hidden is an
unallocated var or memory..resulting in the random result....where ? ...
difficult to say...I engineered some weird results like that when solving
quadratic equations (I need to do that for euclidean 2D curves
intersections .. sometimes, below square-root argument is not the integer
exact 0, but a -0.000000001*i and by sqrt(x) call failed ...that why I
classified my Murphy law-result to " f***g complex numbers" :-( ...
Dominique.
