How I can modify the decimal numbers in a table's column?

I have a table with different values like: 0.5, -0.300, -99, 5, 0, and so on. I want to use the output of this table in a hydrological model so I need to have all values in 1 decimal (even integer values, like 5).

Here is an example:

-5.40000000000000

-2.20000000000000

-3.40000000000000

5

4

-99

0

Are what I have, But I need something like this:

-5.4

-2.2

-3.4

5.0

4.0

-99.0

0.0

I tried something like format long, format long g, and format bank, but they weren't helpful. So if anyone knows the solution I would be grateful if tells me.

Best regards

a = randn(5,1)

a = 5×1

0.1370 -0.9759 -1.3119 2.0201 1.3604

str = sprintf('%.1f\n', a)

str = 
    '0.1
     -1.0
     -1.3
     2.0
     1.4
     '

You want to display the numbers as shown or modify them? In case you want to modify them, you can use

number = -99.32345;          % the number you want to modify
num_str = num2str(number);   % convert it to string
[idx,~]=regexp(num_str,'[.]');   % search for decimal point
num_str(idx+2:end) = [];         % delete everything from idx+2 till end
number = str2num(num_str)        % convert result back to number

You can use this in a loop to modify all of your values.
