Precision number throughout scripts and functions.

I have a script that calls many functions, when I run the script I want matlab to use a specific value of precision throughout. I have seen the documentation https://uk.mathworks.com/help/symbolic/increase-precision-of-numeric-calculations.html but this seems to just increase the precision for one single calculation?

Is there a way to set the precision to run throughout my entire code?

It sets the precision for the uses of that variable, just like setting the data type to single would do.

You need to make sure that all calculations are performed with the vpa-created variables.

You can use "format" command to specify a format such as short, long, shortE, shortG. "doc format" for more information.

If you do want to have complete control of the display format, you need to use "fprintf" command.

Will this just change the display or will it also allow me to store higher precision of my variables throughout the code?

[daniel adams]

In fact "Numeric formats affect only how numbers appear in Command Window output, not how MATLAB® computes or saves them"

[Rik]

format (or fprintf) will only affect the display, not the precision. You are on the right track with vpa if you need more than what double can provide.
