"exponent (expo) overflow"

[Alessandro Languasco <languasc@math.unipd.it>]

Hi all,

I'm writing a GP script in which I have to compute a quite large
power of a matrix. This is fine until I use the exponent L<=2^(23)
but for larger L>=2^(24) I have a

*** for: exponent (expo) overflow

(which in fact is not too surprising; the exponent is quite large....).
But I really need to use larger exponents.

Do you know if is it possible to solve this problem ?
Maybe some default() instruction could be used in this situation,
but I don't know if it is possible and how to do this.

Thanks so much !!

Best regards,
Alessandro
