Template:E
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 × 10<sup>−12</sup> you can write 3.14{e|-12}:
a{e|b} gives a×10b [1]
{10^|b} gives 10b [2]
{10^|-12} gives 10−12 [3]
Delimitation
The template uses the delimitation logic of the {val} template. That is, typing 1.2{e|12341} will produce a delimited exponent (1.2×1012341). See #Forcing text display to turn this off.
Text and number recognition
By default, the template recognizes both text and numbers. That is, typing 3.14{e|-12} will produce 3.14×10−12, with the proper minus sign (−), rather than with a hyphen (-). However, typing A{e|-BC} will produce A×10-BC since BC is not a number. In those cases, you need to write A{e|−BC} to produce the correct A×10−BC.
A minus sign also has to be provided for cases like 1.2×101 − 2 (1.2{e|1 − 2}).
Explicit plus sign
To explicitly display the + character, write 1.2{e|4|plus} which will produce 1.2×10+4.
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{e|-42342|text}, which will display 1.2 × 10-42342 instead of 1.2×10−42342. This can also be used as an alternative to explicitly display the plus sign (1.2{e|+4|text} gives 1.2×10+4), but remember that you also lose delimitation if you do it this way.
