9.1e18

=  9.1 * 1018

Multiplying any number by 10 moves the decimal point to the right one place.

For example.......     2 * 10  =  20

20 * 10  =  200

2.5 * 10  =  25

So, multiplying any number by 10, 18 times,  moves the decimal point to the right 18  places.

For this problem, we need to move the decimal point to the right 18 places.

=  9 100 000 000 000 000 000
