/* Lookup table used in vector erfcf.
   For each possible rounded input r (multiples of 1/64), between
   r = 0.0 and r = 10.0625 (645 values):
   - the first entry __v_erfcf_data.tab.erfc contains the values of erfc(r),
   - the second entry __v_erfcf_data.tab.scale contains the values of
   2/sqrt(pi)*exp(-r^2). Both values may go into subnormal range, therefore
   they are scaled by a large enough value 2^47 (fits in 8 bits).  */
