    jslong

    Build Status codecov npm NPM

    The jslong - is a pure JavaScript implementation of Long class for representing a 64-bit two's-complement integer value.

    $ npm install -save @modern-dev/jslong

    📋 Usage

    import { Long } from '@modern-dev/jslong';
     
    const val = Long.getMinValue().subtract(Long.fromInt(1024)).toString(16);
    console.log(val); // '7ffffffffffffc00'

    Constructor

    /**
     * @param {number} low  The low (signed) 32 bits of the long.
     * @param {number} high  The high (signed) 32 bits of the long.

    Methods

    Method signature Description
    toInt(): number The value, assuming it is a 32-bit integer.
    toNumber(): number The closest floating-point representation to this value.
    isSafeInteger(): boolean if can be exactly represented using number (i.e. abs(value) < 2^53).
    toString(radix?: number): string The textual representation of this value.
    getHighBits(): number The high 32-bits as a signed value.
    getLowBits(): number The low 32-bits as a signed value.
    getLowBitsUnsigned(): number The low 32-bits as an unsigned value.
    getNumBitsAbs(): number Returns the number of bits needed to represent the absolute value of this Long.
    isZero(): boolean Whether this value is zero.
    isNegative(): boolean Whether this value is negative.
    isOdd(): boolean Whether this value is odd.
    equals(other: Long): boolean Whether this Long equals the other.
    notEquals(other: Long): boolean Whether this Long does not equal the other.
    lessThan(other: Long): boolean Whether this Long is less than the other.
    lessThanOrEqual(other: Long): boolean Whether this Long is less than or equal to the other.
    greaterThan(other: Long): boolean Whether this Long is greater than the other.
    greaterThanOrEqual(other: Long): boolean Whether this Long is greater than or equal to the other.
    compare(other: Long): number 0 if they are the same, 1 if the this is greater, and -1 if the given one is greater.
    negate(): Long The negation of this value.
    add(other: Long): Long The sum of this and the given Long.
    subtract(other: Long): Long The difference of this and the given Long.
    multiply(other: Long): Long The product of this and the other.
    div(other: Long): Long This Long divided by the given one.
    modulo(other: Long): Long This Long modulo the given one.
    not(): Long The bitwise-NOT of this value.
    and(other: Long): Long The bitwise-AND of this and the other.
    or(other: Long): Long The bitwise-OR of this and the other.
    xor(other: Long): Long The bitwise-XOR of this and the other.
    shiftLeft(numBits: number): Long This shifted to the left by the given amount.
    shiftRight(numBits: number): Long This shifted to the right by the given amount.
    shiftRightUnsigned(numBits: number): Long This shifted to the right by the given amount, with zeros placed into the new leading bits.
    static fromInt(value: number): Long The corresponding Long value.
    static fromNumber(value: number): Long The corresponding Long value.
    static fromBits(lowBits: number, highBits: number): Long The corresponding Long value.
    static fromString(str: string, opt_radix?: number): Long The corresponding Long value.
    static isStringInRange(str: string, opt_radix: number): boolean Whether the string is within the range of a Long.
