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.
Wrinkles nose - but you're right - can't change this nasty name.
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".
pred and succ have been used elsewhere. They are shorter.
T edit_distance(T a, T b)
Returns the number of floating point representations between values a and b.
Definitely useful. Not convinced by this name, but I'll think about it. Signed sounds obvious but I suspect choice may be more complicated than it seems. Paul --- Paul A Bristow Prizet Farmhouse, Kendal, Cumbria UK LA8 8AB +44 1539561830 & SMS, Mobile +44 7714 330204 & SMS pbristow@hetp.u-net.com
