TAN(3F)                 COMMAND REFERENCE                 TAN(3F)



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.

SEE ALSO
     sin(3m).
