I want to do a calculation which gives answer in float. then i want to store that answer in an array. when i tried to do so, the array is converting that float value to nearby integer. can anybody tell me how to get out of it.

We can not guess what are you doing by just reading the description. Please post your code.

If you declare a variable and insert values later, the type of the variable is not changed:
a = zeros(10, 1, 'uint8');
a(1) = pi;
class(a) % >> UINT8 !
disp(a)
% >> 3
Therefore the variable must be either defined explicitely using the wanted class:
a = zeros(10, 1, 'double');
% or simply: a = zeros(10, 1);
Or let Matlab choose the type automatically by omitting the explicite pre-allocation:
a(10) = theFunction();
Now you can start with the last element for an implicite pre-allocation.
