TAN(3F-SVR3)        RISC/os Reference Manual         TAN(3F-SVR3)



NAME
     tan, dtan - Fortran tangent intrinsic function

SYNOPSIS
     real r1, r2
     double precision dp1, dp2

     r2 = tan(r1)

     dp2 = dtan(dp1)
     dp2 = tan(dp1)

DESCRIPTION
     tan returns the real tangent of its real argument.  dtan
     returns the double-precision tangent of its double-precision
     argument.  The generic tan function becomes dtan as required
     with a double-precision argument.
