I am puzzled by the result of this operation in matlab:
I have a var that equals 3
I am trying to calculate (var-1)*60
instead of getting 120 I get 3000, it may have something to do with number formatting ?

Your variable named var (which is a bad idea, because var already has a meaning in MATLAB) is not 3. It is '3'.
xDouble = 3;
(xDouble-1)*60
xChar = '3';
(xChar-1)*60
The ASCII value of '3' is 51. When you subtract 1 from '3' the result is the double value 50 and 50*60 is 3000.
