c# - Calculating the angle and converting it to degrees -

-

i having trouble getting accurate angle measurement , converting degrees.

i first calculated distance with:

double distance = math.sqrt(deltax + deltay); console.writeline("distance :" + math.round(distance, 3)); console.writeline("");

then tried calculate angle:

double angle = math.atan2(deltay, deltax); double radiantodegree = (angle * 180 / math.pi); math.round((decimal)angle, 3); console.writeline("angle :" + angle)

with inputs such x1=2, y1=2, x2=1, y2=1, angle should measure -135.000 degrees.

the problem not using converted value of angle.

you do:

angle = (angle * 180 / math.pi);

instead of defining radianttodegree never using it. happens right printing angle in radians.

this error has shown on many times, seems. prominent answer issue seems restkit 0.20 — coredata: error: failed call designated initializer on nsmanagedobject class however, solution posted doesn't work me. let's start beginning: i want upload file server. want parse response make sure uploaded. if not, try again later. model has boolean variable called nsnumber *senttoserver purpose (in coredata, bool saved nsnumber ) . because don't know whether sending going successful, save entity coredata model first before sending via restkit. when post request successful, server returns json string this: {"id":14,"created":true} notice that, of course, id not set on coredata model yet, both id , created new informations model. here's model: @interface recording : nsmanagedobject @property (nonatomic, retain) nsstring * audiofilepath; @property (nonatomic, retain) nsdate * createdat; @property (nonatomic, retain) nsstring * deviceid; @
