Template:E

テンプレートの解説[表示] [編集] [履歴] [キャッシュを破棄]

{e}および{10^}は、科学記法の上付き番号（指数表記）を省入力するためのテンプレートです。{10^}は乗算記号（「×」）を生成しない点を除いて{e}とほほ同じ動作を行い、以下の使い方のように動作します。

3.14 × 10^-12を書く際には通常3.14＆nbsp;×＆nbsp; 10 <sup>＆12; </sup>と書きますが、テンプレートを利用すると3.14 {e | -12}と書くことができます。⇒ 3.14 ×10⁻¹²

{e|b} → ×10^b

{10^|b} → 10^b

{10^|-12} → 10⁻¹²

The first output character for {e} is a non-breaking thin-space:

.{e|b}. → .×10^b.

.{10^|b}. → .10^b.

.{10^|-12}. → .10⁻¹².

The template uses gaps or commas, per {val}.
1.2{e|12341} → 1.2×10¹²³⁴¹.

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 1.2×10^{1 − 2} (1.2{e|1 − 2}).

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

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.
