no unsigned 32 bit numbers?

uint8_t a;
a = 10 * -1;
printf("%d \n", a);// prints 246

uint16_t b;
b = 10 * -1;
printf("%d \n", b);// prints 65526

uint32_t c;
c = 10 * -1;
printf("%d\n", c);// prints -10

The above suggests that there is no unsigned 32 bit int available? I'm using the LPC1768. Sorry about the weird example code.
