The tan() function computes the tangent of
x (measured in radians). The
tanf() function is a single precision version of
tan(). The tanl() function
is an extended precision version of tan(). A large
magnitude argument may yield a result with little or no significance.
The tan(), tanf()
and tanl() functions return the tangent value.

(“ANSI C89”).
