    Extract bits from int



      I'm working on a radix-sort algorithm and I need to extract some bits from int values.

      My sort is working fine when I sort on 4,12,20,24,28,32 bits but not on 8 and 16 bits !!!!

      I don't understand the reason, maybe a problem with the way I extract the bits !

      I use the following :


      #define EXTRACT_BIT(VALUE,BIT) ((((uint)VALUE)>>BIT)&0x1)

      #define EXTRACT_4BITS(VALUE,BIT) ((((uint)VALUE)>>BIT)&0x0F)

      Do you have an advice ?
