_cell_volume

Name:
'_cell_volume'

Definition:

   Cell volume V in angstroms cubed.

   V = a b c [1 - cos^2^(alpha) - cos^2^(beta) - cos^2^(gamma)
               + 2 cos(alpha) cos(beta) cos(gamma) ] ^1/2^

   a     = _cell_length_a
   b     = _cell_length_b
   c     = _cell_length_c
   alpha = _cell_angle_alpha
   beta  = _cell_angle_beta
   gamma = _cell_angle_gamma


The permitted range is 0.0 -> infinity
