Hello,
I have the following problem. I should compare some timestamps I have read from an excel file. Basically what I do is creating a vector containing this timestamps converted using the "datenum" command. If i then for example try to visualize the value of the variable, I get the following result on the console:
datenum(textdata{1})
ans =
>> datestr(ans)
ans =
01-Jan-2011 00:00:06
until this point I get it perfectly.
Now, if I have another timestamp which is for example:
01-Jan-2011 00:00:01
and I convert it to a numdate, i get the same result due to the precision which matlab uses to visualize my variable:
datenum(textdata2{1})
ans =
now if I wanna compare them, I was guessin, I can just make a simple if test:
a = 01-Jan-2011 00:00:06; b = 01-Jan-2011 00:00:01;
if a == b disp ('equal') elseif a > b disp ('greater') else disp('smaller') end
greater
So up to this point is everything ok.
After that i increase b of the right quantity to make it the same as a:
b = b + (5/(3600*24)); %now b is 01-Jan-2011 00:00:06;
if a == b disp ('equal') elseif a > b disp ('greater') else disp('smaller') end
smaller
What is happening here? why I don´t get that they are the same? For instance this test gives me 'equal' only if I directly assign a = b.
How can I manage this situation?
