iphone: floats cast to unsigned ints get set to 0 if they are negative!?

try it out:

volatile float bob = -344.0f;
unsigned int fred = (unsigned int)bob;

printf("%d\n",fred);

output will be 0.

obviously I am expecting it to wrap around just as if I had cast from a signed int to an unsgined int (which does wrap and act as expected on the iphone)

we assume it is something to do with the floating point settings.

any ideas?
