A sample code being worth thousands words, here are my little findings. I'm aware that using long all the way may have got me out of trouble, but I wanted to share these weird results that some may consider as a bug. In hosted mode there is no pb. The comments contains the content of the popups in the "gwtcompiled" mode. Tested with gwt 2.1 and 2.2 under Chrome, Firefox4 and IE9:
public class MyApp implements EntryPoint{ public void onModuleLoad() { long m=0, n=0, o=0, p=0, q=0; int i = 0; int j = Integer.MAX_VALUE-1; while (i < j)i++; alert("i==j?" + (i==j) + " but i=" + i +" and j=" + j); //==> i==j?true but i=2147483646 and j=2.147483646E9 // did you notice the "float notation" of j? n = n + j; n = n + j; o = o + i; o = o + i; //given i == j we can suppose that n == o?? alert("n="+n + " o="+o); //firefox, chrome, ie9 ==>n=-4 o=4294967292 p = p + (long)j; p = p + (long)j; alert("n="+n + " o="+o + " p="+p); //firefox, chrome, ie9 ==>n=-4 o=4294967292 p=4294967292 //p == o :) this one was expected. for(int k = 0; k<2; k++){ m = m + j; } //at least m should be equal to n, no? alert("n=" + n +" m=" + m); //firefox, chrome, ie9 ==>n=-4 m=4294967292 } public void alert(String s){ Window.alert(s); } } -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
