      NAME
           log10, alog10, dlog10 - Fortran common logarithm intrinsic
           function

      SYNTAX
           real r1, r2
           double precision dp1, dp2

           r2 = alog10(r1)
           r2 = log10(r1)

           dp2 = dlog10(dp1)
           dp2 = log10(dp1)

      DESCRIPTION
           Log10 returns the common logarithm of its argument, in real
           or double-precision type of the argument.

           Alog10 returns the real common logarithm of its real
           argument.

           Dlog returns the double-precision common logarithm of its
           double-precision argument.

           Log works for real or double arguments, but the other forms
           are for programming clarity.
