C/C++ NaN resolution -


when i'm running code have add elements of vector , renormalize. i'm getting nan i'm hoping resolve this.

for example, when x = [1,2,3] vector<double> compute sum(x) = 6 , find out x/6 setting x[i] = x[i]/sum(x) in x. problem x typically holds large doubles , when compute sum(x) (len(x) large way) nan. how can deal not nan?

changing store long double might work??

have verified vectors not bring nan them? btw - "norm" use not non-negative arbitrary vectors, sure don't want sum abs(x[i])?

i needing creating arraylist , adding integers them. essentially, have card game pulls card , saves id (bcid). want add pulled id arraylist, can avoid pulling same card twice. have setup below, keep getting duplicates. know cards pulling correctly, displays fine - repeated cards, unfortunately. any can provide great! have done best include relevant parts. if need additional information, let me know. public static integer bcid1, bcid2, bcid3, bcid4, bcid5, bcdcid; public static list<integer> usedcards = new arraylist<integer>(); in example below, supposed detect duplicate initialize sequence draw different card. public static void setids() { try { bcid1 = integer.parseint(bc1); usedcards.add(bcid1); } catch(numberformatexception nfe) { } try { bcid2 = integer.parseint(bc2); if (usedcards.contains(bcid2)) { try { bluecard2(ctx); } ...
