Help me please to calcu;ate this:
vpa(exp(710)) = ?
why it = Inf
?

vpa(exp(709)) = have 311 digits
The limitation of vpa is 268435448 digits.

What kind of function I can use instead of exp() to do this?

Tnaks.

Jackfrost:
<SNIP symbolic misunderstanding...


... because, it should read

e=sym('exp(710)');
vpa(e,350)
% otherwise, <vpa> gets an <inf> as input
