TAN intrinsic function
Standard: F77 F90 F95 F2003 F2008
Example Program
<Syntax>
TAN ( X )
X : Real or Complex;
Result : Same type and kind as X.
<Semantics>
The value of the result is an approximation to the tangent of X.
Like many intrinsic functions, this is elemental;
the result has the same shape as X, with the operation being applied elementwise.
If X is of type Real, it specifies the angle in radians.
If X is of type Complex, the real part is interpreted as radians.
