log10(3F)

NAME
     log10, alog10, dlog10, qlog10 - FORTRAN common logarithm intrinsic
     function

SYNOPSIS
     real r1, r2
     double precision dp1, dp2
     real*16 qp1, qp2

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

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

     qp2 = qlog10(qp1)
     qp2 = log10(qp1)

DESCRIPTION
     alog10 returns the real common logarithm of its real argument.  dlog10
     returns the double-precision common logarithm of its double-precision
     argument.  qlog10 returns the real*16 common logarithm of its real*16
     argument.  The absolute value of the argument for alog10, dlog10, and
     qlog10 must be greater than zero.  The generic function log10 becomes a
     call to alog10, dlog10, or qlog10 depending on the type of its argument.
