1.234 × 10⁶eng
That's 1.23× as big as a million, while a billion is 810× bigger. That number has 7 digits before the decimal point.
What it means
How big is that?
Very large and very small numbers are held to about 16 significant digits, which is all a computer can store exactly.
The math
How to convert × 10ⁿ to eng
There is nothing to multiply: the same number is written with the decimal point moved and the moves counted as a power of ten. Engineering notation keeps that power a multiple of three.
Example: 1.234 × 10⁶ × 10ⁿ = 1.234 × 10⁶ eng.
