change numbers 9.95 and 11.32 to strings '09.95' and '11.32'

Hi @Rob,

Thanks for clarifying. So, your goal is to convert these numbers into a string formatted as `'2:03.54'`, where: - The minutes (`m`) should be displayed directly. - The seconds (`s`) should be formatted to always show two digits before the decimal point, even if it's a single digit (i.e., `3.54` should become `03.54`). Here's how you can achieve this in MATLAB:

% Define the numbers
m = 2;
s = 3.54;

% Open a file for writing
fid = fopen('output.txt', 'w');

% Convert m to string
m_str = num2str(m);

% Convert s to string with leading zero for minutes
minutes = floor(s);
seconds = mod(s, 1) * 60; % Convert fractional part to seconds
formatted_time = sprintf('%02d:%.2f', minutes, seconds);

% Write to file
fprintf(fid, '%s\n', [m_str, ':', formatted_time]);

% Close the file
fclose(fid);

Hi @Rob,

Please don’t forget to vote and accept answer for @Walter Robertson. He did provide insightful feedback on the MATLAB code snippet. by identifiying two key issues that need to be addressed:

1. Incorrect Calculation of Seconds: The conversion from the fractional part of `s` to seconds is indeed miscalculated. The line `seconds = mod(s, 1) * 60;` is meant to convert the decimal portion of `s` into seconds, but it should instead take the entire value of `s`, not just its fractional part.

2. Leading Zero Formatting: The formatting of seconds using `sprintf('%02d:%.2f', minutes, seconds);` does not enforce two digits for the whole seconds portion when it is less than 10. This can lead to outputs like '03:1.80' instead of '03:01.80'.
