Method Detail

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)

toString

public static String toString(int v)

toString

public static String toString(long v)

toString

public static String toString(double v)

Parameters:

v - double

Returns:

double as a string

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

Since:

2.14

toString

public static String toString(float v)

Parameters:

v - float

Returns:

float as a string

Since:

2.6

toString

public static String toString(float v,
                              boolean useFastWriter)

Parameters:

v - float

useFastWriter - whether to use Schubfach algorithm to write output (default false)

Returns:

float as a string

Since:

2.14

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

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:

value - float value to check

Returns:

True if number is NOT finite (is Infinity or NaN); false otherwise Since 2.10
