I don’t understand so much from mathemics, but a problem migth be, that your variable i is an integer value.
Something else: What should happen, if (i%2==1) ?
I expect you mean the hole part:
1 2 3 4 5 6 7 8 9 10 11 12 13 | <br /> if (sum%2==0)<br /> sum=sum+1/y;<br /> else sum=sum-1/y;<br /> //The I would put this part into brackets {}.if (i%2==1){ <br /> if (sum%2==0)<br /> sum=sum+1/y;<br /> <br /> else<br /> sum=sum-1/y;orif (i%2==1)<br /> if (sum%2==0)<br /> sum=sum+1/y;else sum=sum-1/y;<br /> |
