The Number.MIN_SAFE_INTEGER
constant represents the minimum safe integer in JavaScript (-(2^53 - 1)
).
To represent integers smaller than this, consider using BigInt
.

The MIN_SAFE_INTEGER
constant has a value of -9007199254740991
(-9,007,199,254,740,991 or about -9 quadrillion). The reasoning behind that number is that JavaScript uses double-precision floating-point format numbers as specified in IEEE 754 and can only safely represent numbers between -(2^53 - 1)
and 2^53 - 1
. 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
object you created.
Number.MIN_SAFE_INTEGER // -9007199254740991 -(Math.pow(2, 53) - 1) // -9007199254740991
