- Parameters:
-
text- literal text to parse
- Returns:
- instantiated Number object
@Deprecated public static Number parseInteger(String text)
Builds a Number from the given integer descriptor. Creates the narrowest type possible, or a specific type, if specified.
- throws:
- NumberFormatException if the number does not fit within the type requested by the type specifier suffix (invalid numbers don't make it here)
- Parameters:
-
text- literal text to parse
- Returns:
- instantiated Number object
