c# - BigInteger.Pow(BigInteger, BigInteger)? -


i'm trying calculate large number, requires biginteger.pow(), need exponent biginteger , not int.

i.e.

biginteger.pow(biginteger)

how can achieve this?

edit: came answer. user dog helped me achieve this. 

public biginteger pow(biginteger value, biginteger exponent) {     biginteger originalvalue = value;     while (exponent-- > 1)         value = biginteger.multiply(value, originalvalue);     return value; }

just aspect of general maths, doesn't make sense. that's why it's not implemented.

think of example: biginteger number 2 , need potentiate 1024. means result 1 kb number (2^1024). imagine take int.maxvalue: then, number consume 2 gb of memory already. using biginteger exponent yield number beyond memory capacity!

if application requires numbers in scale, number large memory, want solution stores number , exponent separately, that's can speculate since it's not part of question.

if your issue exponent variable biginteger, can cast int:

biginteger.pow(biginteger, (int)exponent); // exponent biginteger

i confused how play around asyncio module in python 3.4. have searching api search engine, , want each search request run either parallel, or asynchronously, don't have wait 1 search finish start another. here high-level searching api build objects raw search results. search engine using kind of asyncio mechanism, won't bother that. # no asyncio module used here class search(object): ... self.s = some_search_engine() ... def searching(self, *args, **kwargs): ret = {} # raw searching according args , kwargs , build wrapped results ... return ret to try async requests, wrote following test case test how can interact stuff asyncio module. # here testing script @asyncio.coroutine def handle(f, *args, **kwargs): r = yield f(*args, **kwargs) return r s = search() loop = asyncio.get_event_loop() loop.run_until_complete(handle(s.searching, arg1, arg2, ...)) loop.close() by running pytest, return runtimeerror: task got bad yield : {results s...

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
