Dear Kumar,

for the highest and lowest values use realmax and realmin. To know the size of a variable use size. For example

A = [1,2,3];


ans =

   1   3

If you want to know more details about a variable, use whos instead

whos A

Variables in the current scope:

   Attr Name        Size                     Bytes  Class
   ==== ====        ====                     =====  =====
        A           1x3                         24  double

Total is 3 elements using 24 byte

How can I find the highest and lowest possible values of real data type ?

In C++, we have sizeof() function. Is there anything similar to that in Octave ?
