Hash depends on values. If you keep accuracy constant
then probably you will get the same value. But if
you compute value in one accuracy, increase accuracy
for some intermediate calculations, decrease accuracy
back to original one and recompute, then you can get
different result because FriCAS may use some cached
high accuracy values. Note that several FriCAS
routines to get expected accuracy of final result
increase accuracy for intermediate calculations,
so this may happen even if user does no explicit
change of accuracy.
