# 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

editTo 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×10^{b} [1]

`{{10^|b}}`

gives 10^{b} [2]

`{{10^|-12}}`

gives 10^{−12} [3]

### Delimitation

editThe template uses the delimitation logic of the {{val}} template. That is, typing 1.2{{e|12341}} will produce a delimited exponent (1.2×10^{12,341}). See *#Forcing text display* to turn this off.

### Text and number recognition

editBy 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 1.2×10^{−1} (1.2{{e|1 − 2}}).

### Explicit plus sign

editTo explicitly display the + character, write 1.2{{e|4|plus}} which will produce 1.2×10^{+4}.

### Forcing text display

editTo 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 1.2×10^{+4}), but remember that you also lose delimitation if you do it this way.
