It’s difficult to tell what you want to do. If you want to use fprintf, use the appropriate format descriptor (for example '%d', '%u').
To use the save function, cast the numbers a integers in your code, then save them as such.
For instance to convert ‘epsilon’ to unsigned 16-bit integers:
epsilon = uint16(epsilon);
Use the function that best suits your needs.
The save function will save them as you have defined them, and load will load them as the same data type.
