(\d) At least one digit, saves digit to group $2įinally, the matched text is replaced with E$1$2, that is the literal E, then group $1 (a minus sign if found E-, nothing if found E+) and the group $2 (a single digit). For generic or default data, numbers are formatted according to the current locale in engineering notation. \+?(-?) Either a + or a - if - then save to group $1Ġ* As many 0s as it can match, subject to. To explain, sprintf('%.E',x) formats x in scientific notation with E, e.g. 1 Solution According to num2str documentation, you need to use a format parameter of and precision parameter as follows: num2str (1E4,'. to make a cert important distinction: this is a number format and not an arithmetic operator. We can fix the first case with a token: f2 = In MATLAB, 1e-8 is the notation for a very small number. Engineering notation allows the numbers to explicitly match their. Set the output format to the long engineering format and view the same values. Though similar in concept, engineering notation is rarely called scientific notation. ![]() This is not ideal for all cases: > my_format(5) % Expect 5E0 Set the output format to the long fixed-decimal format and display the. Performing arithmetic, using complex numbers and mathematical functions. ![]() You could use a combination of sprintf and regexprep. I like using MATLABs shortEng notation in the interactive Command Window: > a 123e-12 > disp(a) 1.2300e-10 Scientific notation. ![]()
