LOG(3F)                              SysV                              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.
