0.0000000000453 would be equal to .453 * 10^-10

453000000 would be equal to .453 * 10^9

.453 * 10^-10 is also equal to 4.53 * 10^-11

.453 * 10^9 is also equal to 4.53 * 10^8

From the decimal point, you count the number of digits to the right and that is the number of negative exponents you apply to * 10.

example:

.001 = .001 * 10^0
.001 = .01 * 10^-1
.001 = .1 * 10^-2
.001 = 1.0 * 10^-3
.001 = 10.0 * 10^-4
etc.

from the decimal point, you count the number of digits to the left and that is the number of positive exponents you apply to * 10.

1000.0 = 1000.0 * 10^0
1000.0 = 100.0 * 10^1
1000.0 = 10.0 * 10^2
1000.0 = 1.0 * 10^3
1000.0 = .1 * 10^4
etc.

In your problem:

0.0000000000453 counts 10 digits to the right to get you .453 * 10^-10

it counts 11 digits to the right to get you 4.53 * 10^-11

453000000. counts 9 digit to the left to get .453 * 10^9.

it counts 8 digits to the left to get 4.53 * 10^8
