    Methods

    toExponential

    • toExponential(fractionDigits?: number): string

    • Returns a string containing a number represented in exponential notation.

      Parameters

      • OptionalfractionDigits: number

        Number of digits after the decimal point. Must be in the range 0 - 20, inclusive.

      Returns string

    toFixed

    • toFixed(fractionDigits?: number): string

    • Returns a string representing a number in fixed-point notation.

      Parameters

      • OptionalfractionDigits: number

        Number of digits after the decimal point. Must be in the range 0 - 20, inclusive.

      Returns string

    toLocaleString

    • toLocaleString(
          locales?: string | string[],
          options?: NumberFormatOptions,
      ): string

    • Converts a number to a string by using the current or specified locale.

      Parameters

      • Optionallocales: string | string[]

        A locale string or array of locale strings that contain one or more language or locale tags. If you include more than one locale string, list them in descending order of priority so that the first entry is the preferred locale. If you omit this parameter, the default locale of the JavaScript runtime is used.

      • Optionaloptions: NumberFormatOptions

        An object that contains one or more properties that specify comparison options.

      Returns string

    • toLocaleString(locales?: LocalesArgument, options?: NumberFormatOptions): string

    • Converts a number to a string by using the current or specified locale.

      Parameters

      • Optionallocales: LocalesArgument

        A locale string, array of locale strings, Intl.Locale object, or array of Intl.Locale objects that contain one or more language or locale tags. If you include more than one locale string, list them in descending order of priority so that the first entry is the preferred locale. If you omit this parameter, the default locale of the JavaScript runtime is used.

      • Optionaloptions: NumberFormatOptions

        An object that contains one or more properties that specify comparison options.

      Returns string

    toPrecision

    • toPrecision(precision?: number): string

    • Returns a string containing a number represented either in exponential or fixed-point notation with a specified number of digits.

      Parameters

      • Optionalprecision: number

        Number of significant digits. Must be in the range 1 - 21, inclusive.

      Returns string

    toString

    • toString(radix?: number): string

    • Returns a string representation of an object.

      Parameters

      • Optionalradix: number

        Specifies a radix for converting numeric values to strings. This value is only used for numbers.

      Returns string

    valueOf

    • valueOf(): number

    • Returns the primitive value of the specified object.

      Returns number
