• Any positive value divided by NEGATIVE_INFINITY results in negative zero

• Any negative value divided by NEGATIVE_INFINITY results in positive zero

• Zero multiplied by NEGATIVE_INFINITY results in NaN

• NaN multiplied by NEGATIVE_INFINITY is NaN

• NEGATIVE_INFINITY divided by any negative value other than NEGATIVE_INFINITY is POSITIVE_INFINITY

• NEGATIVE_INFINITY divided by any positive value other than POSITIVE_INFINITY is NEGATIVE_INFINITY

• NEGATIVE_INFINITY divided by NEGATIVE_INFINITY or POSITIVE_INFINITY results in NaN
