How to display with n decimal places in Matlab

Question

I was wondering how to use command to set up displaying with n decimal places in Matlab?

Must n be restricted to some predetermined numbers? Or one can just specify any for n?

Thanks and regards!

Answer 1

You can convert a number to a string with n decimal places using the SPRINTF command:

>> x = 1.23;
>> sprintf('%0.6f', x)

ans =

1.230000

>> x = 1.23456789;
>> sprintf('%0.6f', x)

ans =

1.234568
