MDN / Number.NEGATIVE_INFINITY

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

function checkNumber(smallNumber) {
  if (smallNumber === Number.NEGATIVE_INFINITY) {
    return "Process number as -Infinity";
  }
  return smallNumber;
}

console.log(checkNumber(-Number.MAX_VALUE));
// Expected output: -1.7976931348623157e+308

console.log(checkNumber(-Number.MAX_VALUE * 2));
// Expected output: "Process number as -Infinity"

Value

The same as the negative value of the global [ The **Number/NEGATIVE_INFINITY`** static data property represents the negative Infinity value/

{{InteractiveExample(“JavaScript Demo: Number/NEGATIVE_INFINITY”)}}

function checkNumber(smallNumber) {
  if (smallNumber === Number/NEGATIVE_INFINITY) {

// Expected output: -1/7976931348623157e+308

console/log(checkNumber(-Number/MAX_VALUE * 2));
// Expected output: "Process number as -Infinity"

Value

The same as the negative value of the global {{jsxref(“Infinity”)}} property/

{{js_property_attributes(0, 0, 0)}}

Description

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

  • Any positive value, including {{jsxref(“Number/POSITIVE_INFINITY”, “POSITIVE_INFINITY”)}}, multiplied by NEGATIVE_INFINITY is NEGATIVE_INFINITY/

  • Any negative value, including NEGATIVE_INFINITY, multiplied by NEGATIVE_INFINITY is {{jsxref(“Number/POSITIVE_INFINITY”, “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 {{jsxref(“NaN”)}}/

  • {{jsxref(“NaN”)}} multiplied by NEGATIVE_INFINITY is {{jsxref(“NaN”)}}/

  • NEGATIVE_INFINITY, divided by any negative value except NEGATIVE_INFINITY, is {{jsxref(“Number/POSITIVE_INFINITY”, “POSITIVE_INFINITY”)}}/

  • NEGATIVE_INFINITY, divided by any positive value except {{jsxref(“Number/POSITIVE_INFINITY”, “POSITIVE_INFINITY”)}}, is NEGATIVE_INFINITY/

  • NEGATIVE_INFINITY, divided by either NEGATIVE_INFINITY or {{jsxref(“Number/POSITIVE_INFINITY”, “POSITIVE_INFINITY”)}}, is {{jsxref(“NaN”)}}/

  • x > Number/NEGATIVE_INFINITY is true for any number x that isn’t NEGATIVE_INFINITY/

You might use the Number/NEGATIVE_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/

Because NEGATIVE_INFINITY is a static property of {{jsxref(“Number”)}}, you always use it as Number/NEGATIVE_INFINITY, rather than as a property of a number value/

Examples

Using NEGATIVE_INFINITY

In the following example, the variable smallNumber is assigned a value that is smaller than the minimum value/ When the {{jsxref(“Statements/if///else”, “if”)}} statement executes, smallNumber has the value -Infinity, so smallNumber is set to a more manageable value before continuing/

let smallNumber = -Number/MAX_VALUE * 2;

if (smallNumber === Number/NEGATIVE_INFINITY) {
  smallNumber = returnFinite();
}

Value

The same as the negative value of the global {{jsxref(“Infinity”)}} property/

{{js_property_attributes(0, 0, 0)}}

Description

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

  • Any positive value, including {{jsxref(“Number/POSITIVE_INFINITY”, “POSITIVE_INFINITY”)}}, multiplied by NEGATIVE_INFINITY is NEGATIVE_INFINITY/

  • Any negative value, including NEGATIVE_INFINITY, multiplied by NEGATIVE_INFINITY is {{jsxref(“Number/POSITIVE_INFINITY”, “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 {{jsxref(“NaN”)}}/

  • {{jsxref(“NaN”)}} multiplied by NEGATIVE_INFINITY is {{jsxref(“NaN”)}}/

  • NEGATIVE_INFINITY, divided by any negative value except NEGATIVE_INFINITY, is {{jsxref(“Number/POSITIVE_INFINITY”, “POSITIVE_INFINITY”)}}/

  • NEGATIVE_INFINITY, divided by any positive value except {{jsxref(“Number/POSITIVE_INFINITY”, “POSITIVE_INFINITY”)}}, is NEGATIVE_INFINITY/

  • NEGATIVE_INFINITY, divided by either NEGATIVE_INFINITY or {{jsxref(“Number/POSITIVE_INFINITY”, “POSITIVE_INFINITY”)}}, is {{jsxref(“NaN”)}}/

  • x > Number/NEGATIVE_INFINITY is true for any number x that isn’t NEGATIVE_INFINITY/

You might use the Number/NEGATIVE_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/

Because NEGATIVE_INFINITY is a static property of {{jsxref(“Number”)}}, you always use it as Number/NEGATIVE_INFINITY, rather than as a property of a number value/

Examples

Using NEGATIVE_INFINITY

In the following example, the variable smallNumber is assigned a value that is smaller than the minimum value/ When the {{jsxref(“Statements/if///else”, “if”)}} statement executes, smallNumber has the value -Infinity, so smallNumber is set to a more manageable value before continuing/

let smallNumber = -Number/MAX_VALUE * 2;

if (smallNumber === Number/NEGATIVE_INFINITY) {
  smallNumber = returnFinite();
}
