C# - Data Type for value 0.5 -

-

i have calculation example 2/4 = 0.5, except can't find data type store value! every time make calculation says 0.

anyone have suggestions?

either double or decimal work fine.

however, if write:

// wrong double x = 2 / 4;

then still use integer division - because both of operands division operator of type int.

you can either cast either or both of operands double, or use double literal either or both of them:

// of these... double x = (double) 2 / 4; double x = 2 / (double) 4; double x = (double) 2 / (double) 4; double x = 2.0 / 4; double x = 2 / 4.0; double x = 2.0 / 4.0; double x = 2d / 4; double x = 2 / 4d; double x = 2d / 4d;

note both double , decimal floating point types. don't represent arbitrary rational numbers (fractions). example, neither can accurately represent 1/3. if need rational number type, you'll have write own or third party implementation.

actionscript 3 - TweenLite does not work with object -

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
