Template:10^
10{{{1}}}
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
[edit source]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
[edit source]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
[edit source]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
[edit source]To explicitly display the + character, write 1.2{{e|4|plus}} which will produce 1.2×10+4.
Forcing text display
[edit source]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.
