[boost] [Math/nextafter] A question of naming functions...

Folks I'm looking for some good names for some functions I'm on the brink of 
adding to Boost.Math (all in namespace boost::math::):

T nextafter(T val, T dir)

Returns the next representable floating point value to "val" in the 
direction of "dir".  This name is basically fixed, since it's the one that 
C99 uses.

T next_greater(T val)

Returns the next representable value greater than "val".

T next_less(T val)

Returns the next representable value less than "val".

T edit_distance(T a, T b)

Returns the number of floating point representations between values a and b.

So the questions are: can you think of any better names, or are these OK?

And should edit_distance return a signed or absolute value?

Thanks in advance, John.
