    Re: Yet another 4-place Nat-Haversine Table project?
    From: David Fleming

    Tony,

    Given that hav(x) = hav(-x)   there is no need  for negative angle table.

    Further if concerned about size & given that   1 - hav(x) = hav( 180 - x) there is no need for table for x > 90.

    I would also also reconsider the suggestion of multiplying the entries with few than 4 significant digits by a power of ten.  They could be coded with background colors to tell what power of ten that region of the table represents.

    I appologize for raining on your parade, but you asked.
