Better than the one we currently have. For now in rosapps, so we can test it, if it's all working fine, we should replace the wine one. Changes by me: use pow() instead of cbrt(), as cbrt doesn't work in our tree. I imported the whole codebase, although the mpfr files are not used. I moved the localizations to "lang" and the icons to "res" subfolder. svn path=/trunk/; revision=31512

<p style="margin-top: 0; margin-bottom: 0">When working with pure decimal numbers, the user can enter the numbers in two ways:</p>
|
|
<p style="margin-top: 0; margin-bottom: 0"><u><i>Normal mode</i></u>: each number is entered

its integer part and, eventually, its fractional part.</p>
|
|
<p style="margin-top: 0; margin-bottom: 0"><u><i>Exponential mode</i></u>: the number is entered by typing a mantissa and then an exponent. This

method allows you to write very big or very small numbers that you would not be able to type

in a different manner.</p>
