65   63   * NOTE. This program compute sinpi/cospi(t<0.25) by __k_sin/cos(pi*t, 0.0).
66   64   * This will return a result with error slightly more than one ulp (but less
67   65   * than 2 ulp). If one wants accurate result,  one may break up pi*t in
68   66   * high (tpi_h) and low (tpi_l) parts and call __k_sin/cos(tip_h, tip_lo)
