Any negative value, including {{jsxref(\"Number/NEGATIVE_INFINITY\", \"NEGATIVE_INFINITY\")}}, multiplied by POSITIVE_INFINITY is {{jsxref(\"Number/NEGATIVE_INFINITY\", \"NEGATIVE_INFINITY\")}}. Any positive number divided by POSITIVE_INFINITY is positive zero (as defined in IEEE 754). Any negative number divided by POSITIVE_INFINITY is negative zero (as defined in IEEE 754. Zero multiplied by POSITIVE_INFINITY is {{jsxref(\"NaN\")}}. {{jsxref(\"NaN\")}} multiplied by POSITIVE_INFINITY is {{jsxref(\"NaN\")}}. POSITIVE_INFINITY, divided by any negative value except {{jsxref(\"Number/NEGATIVE_INFINITY\", \"NEGATIVE_INFINITY\")}}, is {{jsxref(\"Number/NEGATIVE_INFINITY\", \"NEGATIVE_INFINITY\")}}. POSITIVE_INFINITY, divided by any positive value except POSITIVE_INFINITY, is POSITIVE_INFINITY. POSITIVE_INFINITY, divided by either {{jsxref(\"Number/NEGATIVE_INFINITY\", \"NEGATIVE_INFINITY\")}} or POSITIVE_INFINITY, is {{jsxref(\"NaN\")}}. Number.POSITIVE_INFINITY > x is true for any number _x_ that isn't POSITIVE_INFINITY.\n\nYou might use the Number.POSITIVE_INFINITY property to indicate an error condition that returns a finite number in case of success. Note, however, that {{jsxref(\"NaN\")}} would be more appropriate in such a case.\n\nBecause POSITIVE_INFINITY is a static property of {{jsxref(\"Number\")}}, you always use it as Number.POSITIVE_INFINITY, rather than as a property of a number value.\n\nAttribution: Adapted from MDN Web Docs under CC-BY-SA-2.5.
