You can always use format long, but I don't know if you can specify the number of decimals more than that.

fprintf('%.12f', ans) %Upto 12 floating points, you can change the value range

if i want after decimal 10 digits, then?

[KALYAN ACHARJYA]

fprintf('%.10f', ans)

"Upto 12 floating points"

Why 12? Where does this limit come from? I don't see this limit mentioned anywhere in the fprintf help, nor is it related to the precisions of either double or single floating point numbers:

When I try 15 decimal digits, it works just fine:

>> X = 0.123456789012345;
>> fprintf('%.15f\n',X)
0.123456789012345

Where did you get this "Upto 12 floating points" limit from?
