  Fun with float Anyone want to hazard a guess as to what this C program prints as output? I'm running it on Mac OS/X 10.6.1 on an Intel Core 2 Duo processor, but this should be IEEE-754-compliant math and return the same results on any processor you like that uses IEEE-754.


#include <stdio.h>

int main(int argc, char *argv[])
{
float basenum = 16777210.0;
float num = 0.0;
int counter = 0;

for(counter=0; counter < 16; counter++) {
num = basenum + counter;
printf("num is: %f\n", num);
}
}

  Mac OS and Win7 Short post today.

I'm generally a mac user, but I need to use windows from time to time. When I have to do this, I use either Vista or WIn7. Using XP feels awkward, and the longer I spend away from it, the less I ever want to see it again.

So, I've been running Vista x64 on my main windows box, and recently attended a Microsoft event at which I received a copy of Win7 Ultimate. This was nice of them. However, it was Win7 Ultimate 32-bit, which I can't use. Aside from the fact that 32-bit windows of any flavor is the primary target for malware writers, my main windows box has 8gb of ram. However, one of the microsoft folk at the event put his email address up for comments and feedback on the launch event. I emailed him to say "Win7 looks great - can I get the x64 version?" He wrote back indicating that he'd look into it. Not long after that, I got an email indicating where to send the 32-bit installer disk to exchange it for a x64 version, with said Microsoft professional cc:ed on the email.

Thanks, Mike Benkovitch!
