In discussing how to access elements of an array, there's the following example: > > <verbatim> > # for M an array of matrices > printf "\n%#12.5\n", M[1] > </verbatim> > > The second line should be > printf "\n%12.5f\n", M[1] Thanks, Peter. There was a typo, but actually what we had in mind in this case was printf "\n%#12.5g\n", M[1] The conversion 'g' for floating-point numbers means "use scientific notation if necessary" (i.e. for very big or very small numbers), and the '#' modifier means, print any trailing zeros to the given precision. With 'g', the "precision" value (here 5) refers to significant digits rather than decimal places. So it's a better choice than 'f' for numbers that might, for all the code-writer knows, be very big or small.
