significant figure for 1234 in matlab

To determine the significant figures in MATLAB for a given number, you can use the sigfigs function from the Symbolic Math Toolbox. Here's an example:

main.m
% Load the Symbolic Math Toolbox
sympref('FloatingPointOutput', false)

% Define the number
num = sym(1234);

% Find the significant figures
sf = sigfigs(num);

% Display the result
disp(sf)

12 lines

This will give you the number of significant figures in num. In this case, since num is 1234, it will give you a result of 4.
