| # ROP_RE is checked against Re(acos op) rounded to the precision PREC_ROP_RE |

| # ROP_IM is checked against Im(acos op) rounded to the precision PREC_ROP_IM |

| # INEX_RE is the ternary value for the real part with the following notation: |
| # "?" ternary value not checked |
| # "+" if ROP_RE is greater than the exact mathematical result |
| # "0" if ROP_RE is exactly the mathematical result |
| # "-" if ROP_RE is less than the exact mathematical result |
| # (m.m. INEX_IM) |
| # rounding modes notation: |
| # "N" is rounding to nearest |
| # "Z" is rounding towards zero |
| # "U" is rounding towards plus infinity |
| # "D" is rounding towards minus infinity |
| # Use prefixes "0b" for values in base two, "0x" for values in base sixteen, |
| # no prefix for value in base ten. |
| # In all bases, "nan" is NaN, "inf" is infinity; |
| # The sign of the result is checked with "+inf", "-inf", "-0", or "+0". |
