Hello, this basically frustrates me a bit, - if I have:
Price = 20074.5;
And I present it in my table like this:
disp(table(Price,'VariableNames',{'answer'}));
answer
_____
20075
I dont get decimals? Anyone know a way around this? I hope there can be some kind of solution without format long/short because I don't want to touch other things
- Best

You get that when format short or format short g or format rat or format hex is in effect.
To work around this without changing your active format, you will need to edit the function getFloatFormats() at roughly line 427 of file toolbox/matlab/datatypes/@tabular/disp.m

You could also convert the table entries to character, if you are not planning to do calculations with them.
Note that all that is affected is display of tables not what is stored in the tables. You can also write a function to display the table in whatever format you want.
function disptable(Table)
old_format = matlab.internal.display.format;
format long
disp(Table)
format(old_format)
end
This work but unfortunately it makes the other values in the table very long :/. I only gave a simple table but there are like 20 columns. E.g. I got a percent column where I just need it to show 0.93 but with format long it show:
0.931214019188181
