How would I represent mathematical expressions in Java

I am 开发者_如何学Gotrying to type the following sentence in the Eclipse editor 8.0 × 10 power 4 - But I am unable to get 4 represented properly, how should I do that?

Judging by your comment on a previous answer, it sounds like you're trying to write the expression like this:

8.0 x 10⁴

The 4 is in superscript - and unless the editor has support for putting text in super/subscript you can't do it without copying and pasting the unicode character representation for superscript 4. (Note, copying the 4 from this example will not give you a superscript 4.)

In HTML (which is how I wrote this here) you would use the <sup> tag.

Generally, when powers are written in plain text, the ^ symbol is used to denote that it is a power, like this:

8.0 x 10^4

8 * Math.pow(10, 4)
