# Electrical Engineering/Subscript and Superscript Numbers.

Question
Dear Cleggsan

http://en.wikipedia.org/wiki/Subscript_and_superscript
http://www.thefreedictionary.com/superscript
http://www.thefreedictionary.com/subscript

Do you feel the Subscript and Superscript can also be used accepting negative numbers, fractional numbers, decimal numbers, complex numbers, trigonometric values, logarithm, antilog, Unicode characters, alphanumeric, mathematical constant, physical constant  etc other than Whole numbers (Integers) in future applications viz Typography, Chemistry, Physics etc

Examples : -3, 2/3, 3.14, −3.5 + 2i, Sin 30, log 100, antilog 2, © (Copyright sign), 3d, λ, G etc

i.e. Superscripts and Subscript accepting other numbers, characters, constants other than whole numbers.

Thanks & Regards,

Of course.  They are used all the time in mathematic and engineering; however, as a student we  wish to stay away from them. In most case the numbers are integers because of their application.  For example adding a superscript to link to the bottom of the page is just for numbering in sequence.  In mathematics they are used to denote a special quantity or dimension and are mathematical operators.

In other words subscripts and superscripts are used in context and relate to the application.

In the above calculator you can compute strange fractional exponents.

Try computing the number 10 raised to the 3.2 power.  You will get: 1584.893192461114

Here is a practical electronic circuit computation for charging a capacitor in an RC circuit.  See the solution to it where e is raised to a fractional power.

Hope this helps.
