    • parseInt

      public static final int parseInt(char[] digitChars, int offset, int len)
      Fast method for parsing integers that are known to fit into regular 32-bit signed int type. This means that length is between 1 and 9 digits (inclusive)

      Note: public to let unit tests call it

    • parseLong

      public static final long parseLong(char[] digitChars, int offset, int len)

    • inLongRange

      public static final boolean inLongRange(char[] digitChars, int offset, int len, boolean negative)
      Helper method for determining if given String representation of an integral number would fit in 64-bit Java long or not. Note that input String must NOT contain leading minus sign (even if 'negative' is set to true).
      Parameters:
      negative - Whether original number had a minus sign (which is NOT passed to this method) or not

      public static final double parseDouble(String numStr) throws NumberFormatException
      Throws:
      NumberFormatException
