c# - Dividing with rest 0 -


i have question. have 2 numbers example:

81 / 9 or 25 / 5 or 12 / 6 , on..... these 2 numbers appear randomly. 

public simplespritesequence[] leftnumbers; public simplespritesequence rightnumbers; public simplespritesequence numberresul; randomizer numbersequence = new randomizer(1, 9);     public void getnumbers() {     if (!numbersequence.randomrule.hasnumbersleft())     {         numbersequence.randomrule.reset();     }     int firstnumberindex = numbersequence.getrandom();     leftnumbers[0].setcurrentspriteindex(firstnumberindex);     if (!numbersequence.randomrule.hasnumbersleft())     {         numbersequence.randomrule.reset();     }     int secondnumberindex = numbersequence.getrandom();     leftnumbers[1].setcurrentspriteindex(secondnumberindex);     if (!numbersequence.randomrule.hasnumbersleft())     {         numbersequence.randomrule.reset();     }     int rightnumberindex = numbersequence.getrandom();     rightnumbers.setcurrentspriteindex(rightnumberindex);      int findex = 10 * (int)leftnumbers[0].currentspriteindex;     int sindex = (int)leftnumbers[1].currentspriteindex;     int number = findex + sindex;     int lindex = (int)rightnumbers.currentspriteindex;     result = number / lindex;     debug.log(number + ":" + lindex + "=" + (math.truncate(result)));    while(math.truncate(result) >= 10)   {       if (!numbersequence.randomrule.hasnumbersleft())       {           numbersequence.randomrule.reset();       }       firstnumberindex = numbersequence.getrandom();      leftnumbers[0].setcurrentspriteindex(firstnumberindex);       if (!numbersequence.randomrule.hasnumbersleft())       {           numbersequence.randomrule.reset();       }       secondnumberindex = numbersequence.getrandom();         leftnumbers[1].setcurrentspriteindex(secondnumberindex);         if (!numbersequence.randomrule.hasnumbersleft())       {           numbersequence.randomrule.reset();       }       rightnumberindex = numbersequence.getrandom();         rightnumbers.setcurrentspriteindex(rightnumberindex);          findex = 10 * (int)leftnumbers[0].currentspriteindex;       sindex = (int)leftnumbers[1].currentspriteindex;       number = findex + sindex;       lindex = (int)rightnumbers.currentspriteindex;       result = number / lindex;   }}

with code operations these: 13:6 = 2 or 24:7 = 3 , on. how operations rest 0? example: 81 : 9 or 24 : 8 or 12 : 6 , on. how put condition?

you should use modulo operator uses % operator-symbol. returns remainder of division, instead of result.

12 % 6 = 0 21 % 3 = 0 21 % 6 = 3

it's nice identify odd , numbers.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
