Converting to Scientific Notation
Step 1 :- Position the decimal point. Place a caret, ^, to the right of the
first nonzero digit, where the decimal point will be placed.
Step 2:- Determine the numeral for the exponent. Count the number
of digits from the decimal point to the caret. This number gives
the absolute value of the exponent on 10.
Step 3:- Determine the sign for the exponent. Decide whether multiplying
by 10nshould make the result of Step 1 larger or smaller. The
exponent should be positive to make the result larger; it should
be negative to make the result smaller.
Converting from Scientific Notation
Multiplying a number by a positive power of 10 makes the number larger,
so move the decimal point to the right n places if n is positive in 10n.
Multiplying by a negative power of 10 makes a number smaller, so
move the decimal point to the left places if │n│ is negative.
If n is 0, leave the decimal point where it is.
