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.
