around 16 000 000 playouts limit

[dsmic]

due to float for playouts, this is the limit :)

The actual limit is between 16 and 17 milion, I forgot to copy :)

bug is critical, as it does not stop thinking, but is going on for ever, as +1 does not change the number of playouts anymore

Good find! A potential fix is just to use a double, but I'm not sure at what point that would break.

Just do answer this question :)

detlef@debian-i7-2600:~/tmp$ cat test.c
#include <stdio.h>
double t;

void main()
{
t=1;
while (1)
{
if (t==t+1) break;
t*=2;
}
printf("max t %f\n",t);
}
detlef@debian-i7-2600:~/tmp$ ./a.out
max t 9007199254740992.000000

Technically we can only safely do half that number of playouts, but it should still take many years to reach that, so we're probably safe :)
