double tan(double x)	Calculate tangent to double precision
long double ltan(long double x)	Calculate tangent to long double precision

Parameter
    

x	Floating point value of angle in radians

Description

These functions calculate the tangent of x.  If x is not within the range [-2pi..+2pi], it is reduced to within this range before the tangent is calculated.
