Class SafeInteger

java.lang.Object

java.lang.Number

com.oracle.truffle.js.runtime.SafeInteger

All Implemented Interfaces:

com.oracle.truffle.api.interop.TruffleObject, Serializable, Comparable<SafeInteger>

public final class SafeInteger
extends Number
implements Comparable<SafeInteger>, com.oracle.truffle.api.interop.TruffleObject

This type represents an integer value in the range of -(2⁵³-1) to -2⁵³-1, i.e. the range of integers that can be safely represented as double values, such that for each n, {n, n - 1, n + 1} are exactly representable as double values.
