-/* tanl(x)
- * Return tangent function of x.
- *
- * kernel function:
- *	__kernel_tanl		... tangent function on [-pi/4,pi/4]
- *	__ieee754_rem_pio2l	... argument reduction routine
- *
- * Method.
- *      Let S,C and T denote the sin, cos and tan respectively on
- *	[-PI/4, +PI/4]. Reduce the argument x to y1+y2 = x-k*pi/2
- *	in [-pi/4 , +pi/4], and let n = k mod 4.
- *	We have
- *
- *          n        sin(x)      cos(x)        tan(x)
- *     ----------------------------------------------------------
- *	    0	       S	   C		 T
- *	    1	       C	  -S		-1/T
- *	    2	      -S	  -C		 T
- *	    3	      -C	   S		-1/T
- *     ----------------------------------------------------------
- *
- * Special cases:
- *      Let trig be any of sin, cos, or tan.
- *      trig(+-INF)  is NaN, with signals;
- *      trig(NaN)    is that NaN;
- *
- * Accuracy:
- *	TRIG(x) returns trig(x) nearly rounded
