      • outputInt

        public static int outputInt​(int v,
                            char[] b,
                            int off)
        Method for appending value of given int value into specified char[].

        NOTE: caller must guarantee that the output buffer has enough room for String representation of the value.

        Parameters:
        v - Value to append to buffer
        b - Buffer to append value to: caller must guarantee there is enough room
        off - Offset within output buffer (b) to append number at
        Returns:
        Offset within buffer after outputting int

      • outputInt

                            byte[] b,
                            int off)

      • outputLong

        public static int outputLong​(long v,
                             char[] b,
                             int off)
        Method for appending value of given long value into specified char[].

        NOTE: caller must guarantee that the output buffer has enough room for String representation of the value.

        Parameters:
        v - Value to append to buffer
        b - Buffer to append value to: caller must guarantee there is enough room
        off - Offset within output buffer (b) to append number at
        Returns:
        Offset within buffer after outputting long

      • notFinite

        public static boolean notFinite​(double value)
        Helper method to verify whether given double value is finite (regular rational number} or not (NaN or Infinity).
        Parameters:
        value - double value to check
        Returns:
        True if number is NOT finite (is Infinity or NaN); false otherwise Since 2.10

        Parameters:
        value - float value to check
        Returns:
        True if number is NOT finite (is Infinity or NaN); false otherwise Since 2.10
