Parameter
Name	Description
value	double

Returns
Type	Description
Quadruple

fromLong(long value)

public static Quadruple fromLong(long value)

Parameter
Name	Description
value	long

Returns

fromString(String s)

public static Quadruple fromString(String s)

Converts a decimal number to a Quadruple. The supported format (no whitespace allowed) is:

• NaN for Quadruple.NaN
• Infinity or +Infinity for Quadruple.POSITIVE_INFINITY
• -Infinity for Quadruple.NEGATIVE_INFINITY
• regular expression: [+-]?[0-9](.[0-9])?(eE?[0-9]+)? - the exponent cannot be more than 9 digits, and the whole string cannot be empty

Parameter

s	String

Returns
Type	Description
Quadruple

Constructors

Quadruple(boolean negative, int biasedExponent, long mantHi, long mantLo)

public Quadruple(boolean negative, int biasedExponent, long mantHi, long mantLo)

Build a new quadruple from its raw representation - sign, biased exponent, 128-bit mantissa.

Parameters
Name	Description
negative	boolean the sign of the number.
biasedExponent	int the unsigned and biased (by 0x7FFF_FFFF) binary exponent.
