4 sty 2013 · I am using fprintf to write my answers to a file. I have numbers such as: 3/7,3/11,6/37... I tried different formats but every time it always changed it to a numeric value. Then I tried format rat before fprintf. This didn't work neither. How can I display a rational number using fprintf?

Write data to a file and return the number of bytes written. Write an array of data, A, to a file and get the number of bytes that fprintf writes. A = magic (4); fileID = fopen ('myfile.txt', 'w'); nbytes = fprintf (fileID, '%5d %5d %5d %5d\n',A) nbytes = 96. The fprintf function wrote 96 bytes to the file.
20 mar 2022 · This issue is relative of converting decimals into fractions inside fprintf. I've tried using "sym", but the points still appear to be decimal.
If you use fprintf to convert a MATLAB double into an integer, and the double contains a value that cannot be represented as an integer (for example, it contains a fraction), MATLAB ignores the specified conversion and outputs the value in exponential format.
Sometimes the ability to output a single value is adequate, but the ability to describe values and the ability to output entire matrices and arrays are more useful. Consider fprintf: fprintf(ID, 'Format text and conversion characters', variable matrix); The second argument is not limited to conversion characters.
Below are several examples of printing information from variables using fprintf. Notice the use of %s to print a string, and %d to print an integer, and %f to print a number with a decimal (a floating point number).
2 lis 2020 · MATLAB overrides the specified conversion, and uses %e ", and this is exactly what you are doing: you specified an integer format with %d but the data has a non-zero fractional part and so fprintf uses %e instead, which for some values may give the same output as the %f format.
