25 # INEX_RE INEX_IM PREC_ROP_RE ROP_RE PREC_ROP_IM ROP_IM PREC_OP_RE OP_RE PREC_OP_IM OP_IM RND_RE RND_IM
27 # where op = op_re + i * op_im, rop = rop_re + i * rop_im,
28 # rop_re is ROP_RE rounded to nearest to the precision of PREC_ROP_RE
29 # rop_im is ROP_IM rounded to nearest to the precision of PREC_ROP_IM
30 # op_re is OP_RE rounded to nearest to the precision of PREC_OP_RE
31 # op_im is OP_IM rounded to nearest to the precision of PREC_OP_IM
32 # ROP_RE is checked against Re(atan op) rounded to the precision PREC_ROP_RE
33 # in the direction RND_RE
34 # ROP_IM is checked against Im(atan op) rounded to the precision PREC_ROP_IM
35 # in the direction RND_IM
36 # INEX_RE is the ternary value for the real part with the following notation:
37 # "?" ternary value not checked
38 # "+" if ROP_RE is greater than the exact mathematical result
39 # "0" if ROP_RE is exactly the mathematical result
40 # "-" if ROP_RE is less than the exact mathematical result
42 # rounding modes notation:
43 # "N" is rounding to nearest
44 # "Z" is rounding towards zero
45 # "U" is rounding towards plus infinity
46 # "D" is rounding towards minus infinity
47 # Use prefixes "0b" for values in base two, "0x" for values in base sixteen,
48 # no prefix for value in base ten.
49 # In all bases, "nan" is NaN, "inf" is infinity;
50 # The sign of the result is checked with "+inf", "-inf", "-0", or "+0".
