LOG(3F)                 COMMAND REFERENCE                 LOG(3F)



NAME
     log, alog, dlog, clog - FORTRAN natural logarithm intrinsic
     function

SYNOPSIS
     real r1, r2
     double precision dp1, dp2
     complex cx1, cx2

     r2 = alog(r1)
     r2 = log(r1)

     dp2 = dlog(dp1)
     dp2 = log(dp1)

     cx2 = clog(cx1)
     cx2 = log(cx1)

DESCRIPTION
     Alog returns the real natural logarithm of its real
     argument.  Dlog returns the double-precision natural
     logarithm of its double-precision argument.  Clog returns
     the complex logarithm of its complex argument.  The generic
     function log becomes a call to alog, dlog, or clog depending
     on the type of its argument.

SEE ALSO
     exp(3m).
