Description davidje13 2014-01-04 15:31:19 UTC 
This code:

int a = 3;
int b = 2;
double c = a / (double) b;

triggers a hint to "remove redundant cast to double", but this obviously leads to integer division instead of floating point division, changing the answer from 1.5 to 1. Same applies to (double) a / b, (double) a / (double) b, and float too.
