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 BigInt
.

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 Number.isSafeInteger()
for more information.
Because MIN_SAFE_INTEGER
is a static property of Number
, you always use it as Number.MIN_SAFE_INTEGER
, rather than as a property of a number value.
Number.MIN_SAFE_INTEGER; // -9007199254740991 -(2 ** 53 - 1); // -9007199254740991
