function value = c8_norm_l1 ( x )

%*****************************************************************************80
%
%% c8_norm_l1() evaluates the L1 norm of a C8.
%
%  Discussion:
%
%    Numbers of equal norm lie along diamonds centered at (0,0).
%
%    The L1 norm can be defined here as:
%
%      C8_NORM_L1(X) = abs ( real (X) ) + abs ( imag (X) )
