One thing to think about is whether the bank would say you have double at 17.4 years or make you wait until the next quarter year ends at 17.5 years. The wikipedia article uses `|__nt__|` , which means round down to the nearest integer, which means that after 17.4 years your investment would only be about 1.98 times the original and you would have to wait another tenth of a year to really double it.
