init(string:locale:)

Initializes a decimal number so that its value is equivalent to that in a given numeric string, interpreted using a given locale.

Declaration

convenience init(string numberValue: String?, locale: Any?)

Parameters

  • numberValue:

    A numeric string.

    Besides digits, numberValue can include an initial + or –; a single E or e, to indicate the exponent of a number in scientific notation; and a single decimal separator character to divide the fractional from the integral part of the number.

  • locale:

    A dictionary that defines the locale (specifically the Decimalseparator) to use to interpret the number in numberValue.

Discussion

The locale parameter determines whether the decimalSeparator is a period (like in the United States) or a comma (like in France).

The following strings show examples of acceptable values for numberValue:

  • 2500.6 (or 2500,6, depending on locale)

  • –2500.6 (or –2500,6)

  • –2.5006e3 (or –2,5006e3)

  • –2.5006E3 (or –2,5006E3)

The following strings are unacceptable:

  • 2,500.6

  • 2500 3/5

  • 2.5006x10e3

  • two thousand five hundred and six tenths
