_ionType: IonType

Static Readonly EPSILON

EPSILON: number

The value of Number.EPSILON is the difference between 1 and the smallest value greater than 1 that is representable as a Number value, which is approximately: 2.2204460492503130808472633361816 x 10‍−‍16.

Static Readonly MAX_SAFE_INTEGER

MAX_SAFE_INTEGER: number

The value of the largest integer n such that n and n + 1 are both exactly representable as a Number value. The value of Number.MAX_SAFE_INTEGER is 9007199254740991 2^53 − 1.

Static Readonly MAX_VALUE

MAX_VALUE: number

The largest number that can be represented in JavaScript. Equal to approximately 1.79E+308.

Static Readonly MIN_SAFE_INTEGER

MIN_SAFE_INTEGER: number

The value of the smallest integer n such that n and n − 1 are both exactly representable as a Number value. The value of Number.MIN_SAFE_INTEGER is −9007199254740991 (−(2^53 − 1)).

Static Readonly MIN_VALUE

MIN_VALUE: number

The closest number to zero that can be represented in JavaScript. Equal to approximately 5.00E-324.

Static Readonly NEGATIVE_INFINITY

NEGATIVE_INFINITY: number

A value that is less than the largest negative number that can be represented in JavaScript. JavaScript displays NEGATIVE_INFINITY values as -infinity.

Static Readonly NaN

NaN: number

A value that is not a number. In equality comparisons, NaN does not equal any value, including itself. To test whether a value is equivalent to NaN, use the isNaN function.

Static Readonly POSITIVE_INFINITY

POSITIVE_INFINITY: number

A value greater than the largest number that can be represented in JavaScript. JavaScript displays POSITIVE_INFINITY values as infinity.

Static _getIonType

Static isFinite

  • isFinite(number: unknown): boolean
  • Returns true if passed value is finite. Unlike the global isFinite, Number.isFinite doesn't forcibly convert the parameter to a number. Only finite values of the type number, result in true.

    Parameters

    • number: unknown

      A numeric value.

    Returns boolean

Static isInteger

  • isInteger(number: unknown): boolean
  • Returns true if the value passed is an integer, false otherwise.

    Parameters

    • number: unknown

      A numeric value.

    Returns boolean

Static isNaN

  • isNaN(number: unknown): boolean
  • Returns a Boolean value that indicates whether a value is the reserved value NaN (not a number). Unlike the global isNaN(), Number.isNaN() doesn't forcefully convert the parameter to a number. Only values of the type number, that are also NaN, result in true.

    Parameters

    • number: unknown

      A numeric value.

    Returns boolean

Static isSafeInteger

  • isSafeInteger(number: unknown): boolean
  • Returns true if the value passed is a safe integer.

    Parameters

    • number: unknown

      A numeric value.

    Returns boolean

Static parseFloat

  • parseFloat(string: string): number
  • Converts a string to a floating-point number.

    Parameters

    • string: string

      A string that contains a floating-point number.

    Returns number

Static parseInt

  • parseInt(string: string, radix?: number): number
  • Converts A string to an integer.

    Parameters

    • string: string
    • Optional radix: number

      A value between 2 and 36 that specifies the base of the number in numString. If this argument is not supplied, strings with a prefix of '0x' are considered hexadecimal. All other strings are considered decimal.

    Returns number
