Re: [xml] Getting crazy with float parsing

Daniel,

You are not turning crazy :) It is a known problem with float numbers
that has origin in the way float numbers are stored in memory. For example,
the following program
       float a = 0.000;

       if(a == 0.00000) {
           printf("Hello!\n");
       }
will probably never print "Hello!"
