Floating Point Comparison C++ - Finding maximum -


When I compare floating point, I get printed inf in the output screen Can help? 

  unsigned longer temporarily; Long double tempDec = 0.0, max = 0.0; Unsigned long maxInd = 0, j = 0; (Unsigned for long I = 1; i & lt; 100; i ++) for {j = i-1; Temporary = 0; While (h> gt; 0) {if (returnGCD (j, i) == 1) {temp ++; } J--; } TempDec = ((long dual) i) / ((double long) temporary); If (tempDec> max) {max = tempDec; maxInd = I; }} Cout & lt; & Lt; Max. & Lt; & Lt; "#" & lt; & Lt; Maximum end lieutenant; & Lt; Endl;   
 When I tried to exclude this snippet, I would like the output  
  inf # 1   
 I do not know what's wrong with this. For only one comparison, we can use fibers (), is there any other special way to find out more numbers in the float?   
 
 
 The loop has its first recurrence,  temp = 0 ,  j = 0  create  tempDec  due to division by 0.  if (tempDec> max)  will be true for the first time and  max From that onwards,  if  will always be false.  
 Fix the code so that you do not divide by 0.

In brief, the wrapper module is inserted during posting and the status of an entry is changed to 'modified' . Before changing the state, the state is set to 'separate', but calling attachments () causes the same error to be thrown away. I am using EF 6.

I use Django 1.6.5 with settings in my program txsite: DEBUG = true I set the lie to debug, but when I get the runner , I get the following error: CommandError: You have to set the settings.
