Converts a Source Number value as the default Java Locale into a String whose format is user-defined by the Locale parameter. For example, passing a number value of "1000.01" to a String defined with the "nl-NL" (Netherlands) locale will result in the value "1.000,01". The format of the Locale needs to be a language tag.
|Source Value||String||The source number value.|
|Source Locale||String||This is the locale that represents the format of the source value.|
If the number value or Locale is NULL then returns NULL.
