How can 8^8^8^8 (and higher such values) equal infinity? Shouldn't it be impossible to reach infinity with any amount of addition or multiplication of finite numbers?
The calculator here has a maximum display of 199! =~10^372. Do you have any understanding how big your number is? You simply cannot comprehend it!!!!.
Some calculators will switch to EXPONENTIAL display...or SCIENTIFIC notation.... you lose some ACCURACY, but at such LARGE numbers it is usually insignificant.......YMMV
The web 2 calc will do that too ElectricPavlov - well it will if you are using it on the home page anway, but this number is just too large large to be displayed.
I just tried it on my casio and i got the same result that is 'maths error'
Wolfram Alpha does give an approximation but few calcs would.
