can someone running on x86 check that this change to Dand_bits() in be_runtime.c still works as expected?

object Dand_bits(d_ptr a, d_ptr b) 
/* double a AND b */ 
{ 
        double maxplus1 = ((double)UINTPTR_MAX) + 1; 
        return and_bits( (uintptr_t)fmod(a->dbl,maxplus1), (uintptr_t)fmod(b->dbl,maxplus1)); 
} 

it seems so far to be working as expected ont eh raspberry pi but i'd like to make sure it isn't mucking up x86

cat and_bits.ex 
-- andbits.ex  
atom index_hash = 0xffff_ffff  
index_hash *= 4  
? index_hash  
index_hash += 10  
? index_hash 
? and_bits( 0xffff_ffff, index_hash )
