%% Format Numbers into Strings % Format |pi| to eight decimal places and return it as a string. A = pi %% formatSpec = string('%.8f') %% str = compose(formatSpec,A) %% % Create a numeric array that contains values of |pi| and |e|. Use the |%e| % and |%f| operators with different precisions. A = [pi exp(1)] %% formatSpec = string('The value of pi is %.2e; the value of e is %.5f.'); str = compose(formatSpec,A)
