Methods

toExponential

toExponential(fractionDigits?): 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?): 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?, options?): 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?, options?): 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?): 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?): 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
