    • 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

      public static int outputInt(int v, 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

    • outputLong

      public static int outputLong(long v, byte[] b, int off)

    • divBy1000

      public static int divBy1000(int number)
      Optimized code for integer division by 1000; typically 50% higher throughput for calculation
      Since:
      2.17

    • toString

      public static String toString(double v)
      Parameters:

    • toString

      public static String toString(double v, boolean useFastWriter)
      Parameters:
      v - double
      useFastWriter - whether to use Schubfach algorithm to write output (default false)
      Returns:
      double as a string

    • toString

      public static String toString(float v)
      Parameters:
      v - float
      Returns:

    • 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

    • notFinite

      public static boolean notFinite(float value)
      Helper method to verify whether given float value is finite (regular rational number} or not (NaN or Infinity).
      Parameters:
