Defined in header <cmath>
float       tan( float arg );
double      tan( double arg );
long double tan( long double arg );
double      tan( Integral arg );
(since C++11)

Computes tangent of arg.

Parameters

arg - floating point value representing angle in radians

Return value

Tangent of arg.

Domain error occurs if arg is infinite. NAN is returned in that case.
