java - Returning zero when it shouldn't -


the method below keeps returning 0, , cannot figure out why! please help!

    currentlocation.setlatitude(38.03211);     currentlocation.setlongitude(-78.51002);

and longitude/latitude of if loc 38.03161, -78.51075,

public double getdistance(historicallocation loc) {      return (double) math.abs(math.sqrt((currentlocation.getlatitude() - loc             .getlatitude())             * (currentlocation.getlatitude() - loc.getlatitude())             + (currentlocation.getlongitude() - loc.getlongitude())             * (currentlocation.getlongitude() - loc.getlongitude())));  }

take squareroot of absolute value, not other way around. coming nan setting 0 or that.

(this fixed it)

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
