I want to increase calculations precision. I want to increase decimal point like 32. Is that possible?

%for example

format long

 a=[1.956272615279882  -0.142399812934086]

%this decimal point isn't enough for me (15).

%I want to produce like;

1.95627261527988211111111111111111 (32);

Do you have the Symbolic Toolbox?

[Walter Roberson]

Do you have the fixed point toolbox?

[Muthu Annamalai]

Or if you only want to print more digits on the screen, you may just lookup

>> help format
>> format long
>> 1/pi

Alternatively if you want more high-precision calculations at risk of losing dynamic range @Walter recommendation should work. @James recommendation of Symbolic toolbox will also work, while being even slower than the fixed point.

Try Multiprecision Computing Toolbox for MATLAB.

It is faster than Symboilc Toolbox and allows programming with arbitrary precision.

If you can formulate your problem to work with integers rather than floating point, then this free toolbox is great:
