%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
