Not sure If I understood your requirement, is this what you are trying to do?
Code:
awk ' NR == 1 {
                print
} NR > 1 {
                for (i=1; i<=NF; i++)
                {
                        if($i ~ /^[0-9]+$/)
                        {
                                $i = log($i) / log(2)
                                printf "%.2f ", $i
                        }
                        else
                                printf "%s ", $i
                }
                printf "\n"
} ' file

mcxalter(1)							  USER COMMANDS 						       mcxalter(1)

  NAME
      mcxalter - various network transformations

  SYNOPSIS
      mcxalter [-imx <fname> (specify matrix input)] [-abc <fname> (specify label input)] [-tab <fname> (use tab file)] [-o <fname> (output)] [-tf
      spec (apply tf-spec to input matrix)]

  DESCRIPTION
      This utility supplies various transformations of networks.

  OPTIONS
      -abc <fname> (label input)
	The file name for input that is in label format.

      -imx <fname> (input matrix)
	The file name for input that is in mcl native matrix format.

      -tab <fname> (use tab file)
	This option causes the output to be printed with the labels found in the tab file.  With -abc this option will, additionally, construct  a
	graph  only on the labels found in the tab file.  If this option is used in conjunction with -imx the tab domain and the matrix domain are
	required to be identical.

      -tf <tf-spec> (transform input matrix values)
	Transform the input matrix values according to the syntax described in mcxio(5).

      -o fname (output file)
	Output file.
