asp.net - Can Math.Round in C# be used for whole integer values? -

-

i have integer 363 example.

any method make 360 or 365?

there's nothing built-in, you're going have code logic yourself. here's 1 such method. (going down clearer, going manageable.)

int number = 363; int roundeddown = number - number % 5; int roundedup = number + (number % 5 > 0 ? (5 - number % 5) : 0);

edit negative numbers, logic gets reversed. 

static int rounduptofive(int number) {     if (number >= 0)         return number + (number % 5 > 0 ? (5 - number % 5) : 0);     else         return number - (number % 5); }  static int rounddowntofive(int number) {     if (number >= 0)         return number - number % 5;     else         return number + (number % 5 < 0 ? (-5 - number % 5) : 0); }

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
