This is segment of code I uses (in C++) in one particular instance to avoid
the infinity problems:
double dTransSpeed = (nNumSequence*2)/fTime;
// If zero, avoid division
if (fTime) {
dTransSpeed = (nNumSequence*2)/fTime;
// If result is still within sensible range, proceed.
// otherwise just skip this calculation as nonsense
if (dTransSpeed < 100000) {
gnNumTimes++;
gdAvgTransSpeed += dTransSpeed;
}
}
Of course you need to adopt your own code and take sensible steps when your
calculations hits the infinity. What those sensible step are, can only you
as the programmer be qualified to judge about
