> BTW, 1.01^8005551212 power is 9.99999999999^99

Mmm I doubt it, more like something close to 1+0.01*8005551212=80055513
isn't it?

I don't know. My calculator hits 9.99999^99 at around 2^334

Excel gives up on the straight calculation too, I had to do it with the help of good old logarithms, base 10 so I would have directly the result as a power of 10 (=~9.999999999999...)

Log(a^b) is b*Log(a) isn't it?

So Log(1.01^8005551212)=8005551212*Log(1.01)
=8005551212*0.00432137378264258
=34594979.1231393

So 1.01^8005551212 = 10^34594979.1231393, and not 10^99 as your calculator wants you to believe ;)

The well know approximation:
(1+epsilon)^n=~1+n*epsilon
on which my previous calculation was based only works for reasonable values of n obviously.
