 ### a lot of new TODOs and a list with some feature requests

`svn path=/trunk/kdeextragear-1/kbruch/; revision=176964`

 what is left to do ================== * use another font size from KGlobalSettings * find a better way to align task and statistical window * use function pow() from math.h instead of high() * remove #define TRUE and use datatype bool * maybe use int instead of short because source easier to read * document classes to be able to use KDoc * maybe use kdDebug() vor debug messages * split class task in representation, calculate and generation * integrate KBruch as part into KMath feature request =============== - a visual representation of fractions in circles, rectangeles, ... for beginners - the possibility to practic conversions from fractions to decimal numbers and vica versa. 1/8 = 0.125 - the calculation with 'mixed numbers' like 2 1/3 + 5 1/7 = - train actions like 1/3 = 3/9 or 15/45 = 1/3. I don't know the Englisch words for this actions. there's also an algorithm to convert decimal numbers of infinite length, but with a repeating part ( which means the decimal representations of all rational numbers ) into fractions... I think the idea was to divide the repeating part by a number which you write down as x 9's where x is the length of the repeating part ( that's the best i can explain it in english :). E.g. 0,111... would become 1/9 . 0.1212... would become 12/99 etc. This is the way they explained it to us in high school, i'm sure there's an easy way to write this down in code... With a being your periodical decimal number and n being the length of the period, you multiply a by 10^n and then subtract a: a = 0.1111111 10a = 1.1111111 9a = 1 a = 1 / 9 b = 0.213213213213 1000b = 213.213213213213 999b = 213 b = 213 / 999
