67   65   * NOTE. This program compute sinpi/cospi(t<0.25) by __k_sin/cos(pi*t, 0.0).
68   66   * This will return a result with error slightly more than one ulp (but less
69   67   * than 2 ulp). If one wants accurate result,  one may break up pi*t in
70   68   * high (tpi_h) and low (tpi_l) parts and call __k_sin/cos(tip_h, tip_lo)
71   69   * instead.
