LOG(3F-SysV)        RISC/os Reference Manual         LOG(3F-SysV)



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 argu-
     ment.  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.
