exp(3F)                                                   exp(3F)



NAME
     exp, dexp, cexp, zexp, cdexp - Fortran exponential intrinsic
     function

SYNOPSIS
     real r1, r2
     double precision dp1, dp2
     complex cx1, cx2
     double complex dx1, dx2

     r2 = exp(r1)

     dp2 = dexp(dp1)
     dp2 = exp(dp1)

     cx2 = clog(cx1)
     cx2 = exp(cx1)

     dx2 = cdlog(dx1)
     dx2 = zlog(dx1)
     dx2 = log(dx1)

DESCRIPTION
     exp returns the real exponential function e**x of its real
     argument.  dexp returns the double-precision exponential
     function of its double-precision argument.  cexp returns the
     complex exponential function of its complex argument.  zexp
     and cdexp return the double-precision complex exponentials
     function of their double-precision complex argument.  The
     generic function exp becomes a call to dexp, cexp or zexp as
     required, depending on the type of its argument.

SEE ALSO
     exp(3M).
