java - Calculate the number of times to divide by two -

-

greetings.

i have java method consider expensive, , i'm trying replace calls mathematical expression. problem is, suck @ math. mean really suck.

the following should explain pattern i'm trying exploit.

f(x)   -> y f(x*2) -> f(x)+1

that is, whenever double value x, value y 1 greater x/2. here example output:

f(5)   -> 6 f(10)  -> 7 f(20)  -> 8 f(40)  -> 9 f(80)  -> 10 f(160) -> 11 f(320) -> 12

my current approach brute force. i'm looping on x , test how many times can halve before reach 5, , add 6. works , faster call original method. looking more "elegant" or potentially cheaper solution.

accepted answer goes 1 manages me without pointing out how stupid :)

(the title sucks, because don't know i'm looking for)

have considered looking @ divide five, find power of 2 have, , add 6 power?

the general approach "given y find out power of x is" use logarithms. calculator try dividing log of 64 log of 2 , see 6.

so - divide five, take log, divide log of two, , add six.

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

-
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.
