Scientific Notation: m x 10n, 1 ≤ m < 10 and n is an integer
Conversion Procedure for a Given Number in Standard Form:
- Move the decimal point to where there is only one digit greater than 0 to its left
- Moving the decimal point n places to the left corresponds to a positive n (n), and moving the decimal point n places to the right corresponds to a negative n (-n)
- m is equal to the number formed by the digit to the left of the new decimal point location, and any digit(s) to its right less trailing 0s
Application of Conversion Procedure to 80,790,000,000,000,000 (80,790,000,000,000,000.0)
- There are 17 digits to the left of the decimal point
- Therefore the decimal point needs to be moved 16 places to the left (n = 16)
- After the decimal point is moved, the digit to its left is 8, and less the trailing 0s, the digits to its right are 079
- As a result, m = 8.079
- In Scientific Notation: 80,790,000,000,000,000 = 8.079 x 1016
