Method Detail

### isDigit

    public static boolean isDigit(char c)

  Returns true if the specified character is a base-10 digit.

### isHexDigit

    public static boolean isHexDigit(char c)

  Returns true if the specified character is a base-16 digit.

### isNumericTypeSpecifier

    public static boolean isNumericTypeSpecifier(char c, boolean isDecimal)

  Returns true if the specified character is a valid type specifier for a numeric value.

### isOctalDigit

    public static boolean isOctalDigit(char c)

  Returns true if the specific character is a base-8 digit.

### parseDecimal

    public static Number parseDecimal(String text)

  Builds a Number from the given decimal descriptor. Uses BigDecimal, unless, Double or Float is requested.
  param:
    text literal text to parse
  return:
    instantiated Number object
  throws:
    NumberFormatException if the number does not fit within the type
  requested by the type specifier suffix (invalid numbers don't make it here)

### parseInteger

    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.
  param:
    text literal text to parse
  return:
    instantiated Number object
  throws:
    NumberFormatException if the number does not fit within the type
  requested by the type specifier suffix (invalid numbers don't make it here)
