Examples of errors detected by the V6094 diagnostic

V6094. The expression was implicitly cast from integer type to real type. Consider utilizing an explicit type cast to avoid the loss of a fractional part.

V6094 The expression was implicitly cast from 'int' type to 'double' type. Consider utilizing an explicit type cast to avoid the loss of a fractional part. An example: double A = (double)(X) / Y;. ProbabilityWeightedMoments.java(130)

public static <A> double[] alphaBetaPWM(...., final int nmom) {
    final int n = adapter.size(data);
    final double[] xmom = new double[nmom << 1];
    double aweight = 1. / n, bweight = aweight;
    for(int i = 0; i < n; i++) {
        ....
        for(int j = 1, k = 2; j < nmom; j++, k += 2) {
            xmom[k + 1] += val * (aweight *= (n - i - j + 1) / (n - j + 1));
            xmom[k + 1] += val * (bweight *= (i - j + 1) / (n - j + 1));

V6094 The expression was implicitly cast from 'int' type to 'double' type. Consider utilizing an explicit type cast to avoid the loss of a fractional part. An example: double A = (double)(X) / Y;. JobHealer.java 41

public class JobHealer extends JobInterface {
  public int range = 5;
  ....
  public boolean aiShouldExecute() {
    healTicks++;
    if (healTicks < speed * 10)
      return false;

    for (Object plObj : npc.worldObj.getEntitiesWithinAABB(
                          EntityLivingBase.class,
                          npc.boundingBox.expand(range, range/2, range)) // <=

    return !toHeal.isEmpty();
  }
}

All arguments of the 'expand' method have 'double' parameters, which results in half of the block being lost during division.
