 =item bool ecb_big_endian ()
 =item int ecb_ctz64 (uint64_t x)
 Returns the index of the least significant bit set in C<x> (or
 equivalently the number of bits set to 0 before the least significant bit
 set), starting from 0. If C<x> is 0 the result is undefined.
+For smaller types than C<uint32_t> you can safely use C<ecb_ctz32>.
 For example:
   ecb_ctz32 (3) = 0
   ecb_ctz32 (6) = 1
 This function is similar to the "count leading zero bits" function, except
 that that one returns how many zero bits are "in front" of the number (in
 the given data type), while C<ecb_ld> returns how many bits the number
 itself requires.
+For smaller types than C<uint32_t> you can safely use C<ecb_ld32>.
 =item int ecb_popcount32 (uint32_t x)
 =item int ecb_popcount64 (uint64_t x)
-Returns the number of bits set to 1 in C<x>. For example:
+Returns the number of bits set to 1 in C<x>.
+For smaller types than C<uint32_t> you can safely use C<ecb_popcount32>.
+For example:
   ecb_popcount32 (7) = 3
   ecb_popcount32 (255) = 8
