MDN / Number.MIN_SAFE_INTEGER

The Number.MIN_SAFE_INTEGER static data property represents the minimum safe integer in JavaScript, or -(253 - 1).

To represent integers smaller than this, consider using [ The **Number/MIN_SAFE_INTEGER`** static data property represents the minimum safe integer in JavaScript, or -(253 - 1)/

To represent integers smaller than this, consider using {{jsxref(“BigInt”)}}/

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

const x = Number/MIN_SAFE_INTEGER - 1;
const y = Number/MIN_SAFE_INTEGER - 2;

console/log(Number/MIN_SAFE_INTEGER);
// Expected output: -9007199254740991

console/log(x);
// Expected output: -9007199254740992

console/log(x === y);
// Expected output: true

Value

-9007199254740991 (-9,007,199,254,740,991, or about -9 quadrillion)/

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

Description

Double precision floating point format only has 52 bits to represent the mantissa, so it can only safely represent integers between -(253 – 1) and 253 – 1/ Safe in this context refers to the ability to represent integers exactly and to correctly compare them/ For example, Number/MIN_SAFE_INTEGER - 1 === Number/MIN_SAFE_INTEGER - 2 will evaluate to true, which is mathematically incorrect/ See {{jsxref(“Number/isSafeInteger()”)}} for more information/

As mentioned in {{jsxref(“Number/EPSILON”)}}, the precision of numbers depends on their magnitude/ Number/MIN_SAFE_INTEGER represents the smallest value at which integer-level operations can be performed precisely, but you can still perform meaningful arithmetic on numbers more negative than that, just without integer-level precision/ The largest representable number in JavaScript is actually {{jsxref(“Number/MAX_VALUE”)}}, which is approximately 1/7976931348623157 × 10308/

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

Examples

Using MIN_SAFE_INTEGER

Number/MIN_SAFE_INTEGER; // -9007199254740991
-(2 ** 53 - 1); // -9007199254740991

Description

Double precision floating point format only has 52 bits to represent the mantissa, so it can only safely represent integers between -(253 – 1) and 253 – 1/ Safe in this context refers to the ability to represent integers exactly and to correctly compare them/ For example, Number/MIN_SAFE_INTEGER - 1 === Number/MIN_SAFE_INTEGER - 2 will evaluate to true, which is mathematically incorrect/ See {{jsxref(“Number/isSafeInteger()”)}} for more information/

As mentioned in {{jsxref(“Number/EPSILON”)}}, the precision of numbers depends on their magnitude/ Number/MIN_SAFE_INTEGER represents the smallest value at which integer-level operations can be performed precisely, but you can still perform meaningful arithmetic on numbers more negative than that, just without integer-level precision/ The largest representable number in JavaScript is actually {{jsxref(“Number/MAX_VALUE”)}}, which is approximately 1/7976931348623157 × 10308/

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

Examples

Using MIN_SAFE_INTEGER

Number/MIN_SAFE_INTEGER; // -9007199254740991
-(2 ** 53 - 1); // -9007199254740991
