.TH EXP 3F .SH NAME exp, dexp, cexp \- Fortran exponential intrinsic function .SH SYNOPSIS .nf .B "real r1, r2" .B "double precision dp1, dp2" .B "complex cx1, cx2" .P .B "r2 = exp(r1)" .P .B "dp2 = dexp(dp1)" .B "dp2 = exp(dp1)" .P .B "cx2 = clog(cx1)" .B "cx2 = exp(cx1)" .SH DESCRIPTION .I Exp\^ returns the real exponential function .I e\u\s-2x\s0\d of its real argument. .I Dexp\^ returns the double-precision exponential function of its double-precision argument. .I Cexp\^ returns the complex exponential function of its complex argument. The generic function .I exp\^ becomes a call to .I dexp\^ or .I cexp\^ as required, depending on the type of its argument. .SH SEE ALSO exp(3M). .\" @(#)exp.3f 5.2 of 5/18/82
