Scientific notation is a way of representing numbers, usually very large or very small, in the form
a*10b where 1 ≤ |a| < 10 is a decimal number and b is an integer (negative or positive).
a is called the mantissa and b is called the exponent.
To convert a number to scientific notation:
· If the number has no decimal point, then add one at the end.
· Then move the decimal point to just after the first digit while counting the number of places you have moved it.
· The new number, formed after moving the decimal point is a.
· The number of places to the left that the decimal point was moved is b. If it was moved to the right, then b is negative.
For example:
23045.06 becomes 2.304506*104
0.00023004 becomes 2.3004*10-4
