10Expression error: Unrecognized punctuation character "{".

Documentation icon Template documentation[view] [edit] [history] [purge]

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&nbsp;×&nbsp;10<sup>&minus;12</sup> you can write 3.14{{e|-12}}:





The template uses the delimitation logic of the {{val}} template. That is, typing 1.2{{e|12341}} will produce a delimited exponent (1.2×1012,341). 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×10Expression error: Unrecognized word "bc". since BC is not a number. In those cases, you need to write A{{e|&minus;BC}} to produce the correct A×10Expression error: Unrecognized word "bc"..

A minus sign also has to be provided for cases like 1.2×10−1 (1.2{{e|1 &minus; 2}}).

Explicit plus sign

To explicitly display the + character, write 1.2{{e|4|plus}} which will produce 1.2×10Expression error: Unrecognized punctuation character "&"..

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 1.2×10−42,342. This can also be used as an alternative to explicitly display the plus sign (1.2{{e|+4|text}} gives 1.2×10Expression error: Unrecognized punctuation character "&".), but remember that you also lose delimitation if you do it this way.
