Quoting from:
By default, MATLAB® uses 16 digits of precision.
But why when I write 900000000+2 (8 zeros after 9) it returns 900000002 but writing 900000000+2 (9 zeros after 9)returns 9.0000e+09 isn't this an 8 digit precision?

That is just a display artifact. The entire number is still there in memory. Do this to change the display format
format longg
and then repeat your test.
