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.
