+%DOUBLE2INT Convert structure values from double to int if precision can be
+%preserved.
+% 
+% EXAMPLE: 
+%   p.value1 = 10.25;
+%   p.value2 = 2;
+% 
+%   p_int = double2int(p);
+%   
+%   p_int.value1
+%       ans = 
+%         10.2500
+%
+%   p_int.value2
+%       ans = 
+%         uint32
+%         2
