Number.NEGATIVE_INFINITY

The Number.NEGATIVE_INFINITY static data property represents the negative Infinity value.

The Number.NEGATIVE_INFINITY value behaves slightly differently than mathematical infinity:

Any positive value, including POSITIVE_INFINITY, multiplied by NEGATIVE_INFINITY is NEGATIVE_INFINITY. Any negative value, including NEGATIVE_INFINITY, multiplied by NEGATIVE_INFINITY is POSITIVE_INFINITY. Any positive value divided by NEGATIVE_INFINITY is negative zero (as defined in IEEE 754). Any negative value divided by NEGATIVE_INFINITY is positive zero (as defined in IEEE 754). Zero multiplied by NEGATIVE_INFINITY is NaN. NaN multiplied by NEGATIVE_INFINITY is NaN. NEGATIVE_INFINITY, divided by any negative value except NEGATIVE_INFINITY, is POSITIVE_INFINITY. NEGATIVE_INFINITY, divided by any positive value except POSITIVE_INFINITY, is NEGATIVE_INFINITY. NEGATIVE_INFINITY, divided by either NEGATIVE_INFINITY or POSITIVE_INFINITY, is NaN. x > Number.NEGATIVE_INFINITY is true for any number x that isn’t NEGATIVE_INFINITY.
