sprintf bug?

I run the following lines to reformat my integer data into string sprintf('%024.0f',1000010000000000000000);

and i expect the result to be

001000010000000000000000

but it's 001000009999999999900000

can someone explain this?

thanx in advance..

It has to do with the size of the value you are entering; it is larger than the largest integer-valued floating-point number (2^52) allowed. It is being resolved to the value that you are seeing as the output.

2^53-1, see BITMAX. http://www.mathworks.de/support/tech-notes/1100/1108.html
