Java Newbie can't do simple Math, operator error
- by elguapo-85
Trying to do some really basic math here, but my lack of understanding of Java is causing some problems for me.
double[][] handProbability = new double[][] {{0,0,0},{0,0,0},{0,0,0}};
double[] handProbabilityTotal = new double[] {0,0,0};
double positivePot = 0;
double negativePot = 0;
int localAhead = 0;
int localTied = 1;
int localBehind = 2;
//do some stuff that adds values to handProbability and handProbabilityTotal
positivePot =
(handProbability[localBehind][localAhead] +
(handProbability[localBehind][localTied] / 2.0) +
(handProbability[localTied][localAhead] / 2.0) ) /
(handProbabilityTotal[localBehind] + (handProbability[localTied] / 2.0));
negativePot =
(handProbability[localAhead][localBehind] +
(handProbability[localAhead][localTied] / 2.0) +
(handProbability[localTied][localBehind] / 2.0) ) /
(handProbabilityTotal[localAhead] + (handProbabilityTotal[localTied] / 2.0));
The last two lines are giving me problems (sorry for their lengthiness).
Compiler Errors:

Not really sure what the problem is. You shouldn't need anything special for basic math, right?
