แม่แบบ:X10^/doc

(เปลี่ยนทางจาก แม่แบบ:E/doc)

The {{10^}} and {{x10^}} 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.

Usage

To render 3.14×10−12, instead of writing 3.14&nbsp;&times;&nbsp;10<sup>&minus;12</sup> you can write 3.14{{x10^|-12}}:

{{x10^|b}}×10b

{{10^|b}}10b

{{x10^|-12}}×10−12

{{10^|-12}}10−12

The first output character for {{x10^}} is a non-breaking thin-space (“]” and “[” are used to illustrate the effects):

]{{x10^|b}}[]×10b[

]{{10^|b}}[]10b[

]{{x10^|-12}}[]×10−12[

]{{10^|-12}}[]10−12[

Delimiters

The template uses gaps or commas, per {{val/delimitnum}}.
1.2{{x10^|12341}}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{{x10^|-12}} will produce 3.14×10−12, with the proper minus sign (“”), rather than with a hyphen (“-”). However, typing A{{x10^|-BC}} will produce A×10-BC since BC is not a number. In those cases, you need to write A{{x10^|&minus;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{{x10^|1 &minus; 2}}).

Explicit plus sign

To explicitly display the + character, write 1.2{{x10^|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{{x10^|&minus;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{{x10^|+4|text}} gives 1.2×10+4), but remember that you also lose delimitation if you do it this way.
