Scientific Notation

##
Basic Concept

**Exponential Notation**
expresses any number as a product of two numbers, a decimal and a
power of 10, e.g. 11x103. This notation is often used to express very
large or small numbers.

**Scientific Notation** is a
more systematic form of exponential notation, which is used widely by
chemists. It is a form that the number is expressed with one (and
only one) non-zero digit to the left of the decimal point and an
integer exponent or power of ten, e.g. 6.023x1023.

##
Feature Overview

This module allows conversion between numerical notation (102.01) and
scientific notation (1.0201x102). and its algebraic operations.

##
User Instructions

Special Input Instruction: To enter an exponent, use either e-form,
for example, to type in 1.1x102, enter 1.1e2.

####
1. Conversion to Scientific Notation

*This convert
numerical notation to scientific notation.*

Enter a number in numerical notation and click **=**
to output the corresponding scientific notation on the right.

####
2. Conversion from Scientific Notation

*This does the
reversal of above operation, converts scientific notation back to
numerical notation.*

Enter an exponential number, using the e-form, e.g. 1.01e-3. Click **=**
to get the result.

####
3. Addition, Subtraction, Multiplication and Division

These allow algebraic operation of any two given numbers in
exponential form and output the result in the same form with the
proper significant figures.
