The optional argument COUNT_RATE is a scalar integer thatprovides the number of clock ticks per second. The optional argument COUNT_MAX is a scalarinteger that provides the value of the maximum count possible.The number of tics per second is always 1000. This routine is implemented on most systems usinggettimeofday(2); some implementations use dclock(3).Return ValueThe arguments of this subroutine are modified during the call; there is no return value.TAN 77Return the tangent of the specified value.SynopsisTAN(X)ArgumentThe argument X must be of type real and have absolute value
