How to get rid of exp in answer

I have evaluated a polynomial of the 6th order.

One of the calculated coefficients has a value of -4.1275e-05 (format short g).

How can I represent this answer as a "normal" number without exp?

Use 'fprintf' with the fixed-point format type %f. For example with your value you could use fprintf('%12.9f',value) to get -0.000041275

Hei! Thank you. It works. The only thing I did not get is this - '%12.9f'. Would you explain me please what does it mean?

[Roger Stafford]

The % on the left and f on the right mean fixed-point type format. The 12 is the total field width and the 9 is the number of digits after the decimal point. You can read all about the format specs in the site:

Note that these format specs for matlab's fprintf are very similar to those of the C language for printf.
