create a program that gives you the number of significant digit for any number in matlab

main.m
function [significant_digits] = count_significant_digits(number)
% COUNT_SIGNIFICANT_DIGITS Calculate the number of significant digits for a given number
%
%   [significant_digits] = COUNT_SIGNIFICANT_DIGITS(number) returns the number of significant digits for the given number.
%
%   Example usage:
%
%   >> count_significant_digits(123.456)
%   ans =
%        6

% Convert the number to a string
number_str = num2str(number);

% Find the position of the decimal point
decimal_position = strfind(number_str, '.');

% Count the number of digits before and after the decimal point
digits_before_decimal = length(number_str(1:decimal_position-1));
digits_after_decimal = length(number_str(decimal_position+1:end));

% If the number is an integer, there are no digits after the decimal point
if isempty(digits_after_decimal)
    significant_digits = digits_before_decimal;
else
    significant_digits = digits_before_decimal + digits_after_decimal;
