Template:E/doc

The e and 10^ templates are intended to facilitate and make uniform scientific notation numbers. The 10^ template works exactly as described below except that it does not generate a multiplication (“×”) symbol.

Basic usage
To render 3.14 × 10−12, instead of writing 3.14&amp;nbsp;×&amp;nbsp;10&amp;minus;12 you can write 3.14:

Delimitation
The template uses the delimitation logic of the val template. That is, typing 1.2 will produce a delimited exponent (1.2). See  to turn this off.

Text and number recognition
By default, the template recognizes both text and numbers. That is, typing 3.14 will produce 3.14, with the proper minus sign (&minus;), rather than with a hyphen (-). However, typing A will produce A since BC is not a number. In those cases, you need to write A to produce the correct A.

A minus sign also has to be provided for cases like 1.2 (1.2).

Explicit plus sign
To explicitly display the + character, write 1.2 which will produce 1.2.

Forcing text display
To force the template to display the input as text, and forgo the automatic delimitation and the recognition of the hyphen as a minus sign, write 1.2, which will display 1.2 &times; 10-42342 instead of 1.2. This can also be used as an alternative to explicitly display the plus sign (1.2 gives 1.2), but remember that you also lose delimitation if you do it this way.
