How to stop displaying scientific notation

This calculates a couple different things and I want the answers to be up to 3 decimal places.

Hi RetiredCheetoXI,

From my understanding, you want the output data to be in fixed floating-point notation instead of scientific notation. Moreover, it should be up to 3 decimal places.

You can use %f formatting operator instead of %d to achieve this-

fprintf('Temperature: %.3fk\n\n', T)

Where .3 before the f denotes the number of decimal places (in this case three).

For more details, you can refer to the fprintf documentation-
