Dear list,

If I try to calculate the inverse_fft of an Array using the fft package I sometimes arrive at the following error message:

Error in MACSYMA-TOP-LEVEL [or a callee]: ((MTIMES SIMP)

0.0072416001812632422

((%COS SIMP)

((MTIMES SIMP) 1.0 $%PI))) is not of type (OR

RATIONAL

LISP:FLOAT).

0.0072416001812632422

((%COS SIMP)

((MTIMES SIMP) 1.0 $%PI))) is not of type (OR

RATIONAL

LISP:FLOAT).

Strangely enough if I print out the Array and paste it into another maxima instance the inverse fft Returns an Array instead. So I'm still fighting to produce a reproducible example.

I think the error is on my side but do not seem to find it. Does anybody have an idea where to look to find it?

thanks a lot,

and Kind regards,

Gunter.
