 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. A common use
-case is to compute the integer binary logarithm, i.e.,  C<floor (log2
-(n))>. For example:
+set), starting from 0. If C<x> is 0 the result is undefined. For example:
 
   ecb_ctz32 (3) = 0
   ecb_ctz32 (6) = 1
