Public Methods
public BigInteger add (BigInteger a, BigInteger b)
public BigInteger and (BigInteger a, BigInteger b)
public BigInteger clearbit (BigInteger a, int n)
public int compare (BigInteger a, BigInteger b)
public int compareU (BigInteger a, BigInteger b)
public BigInteger create (String val)
Create a new big integer. The client is responsible for making sure that the two-complement
representation of the value fits within bitsize bits.
public BigInteger[] div2S (BigInteger a, BigInteger b)
public BigInteger[] div2U (BigInteger a, BigInteger b)
public BigInteger divS (BigInteger a, BigInteger b)
public BigInteger divU (BigInteger a, BigInteger b)
public int getBitsize ()
public BigInteger mul2S (BigInteger a, BigInteger b)
public BigInteger mul2U (BigInteger a, BigInteger b)
public BigInteger mulS (BigInteger a, BigInteger b)
public BigInteger mulU (BigInteger a, BigInteger b)
public BigInteger neg (BigInteger a)
public BigInteger not (BigInteger a)
public BigInteger or (BigInteger a, BigInteger b)
public BigInteger remS (BigInteger a, BigInteger b)
public BigInteger remU (BigInteger a, BigInteger b)
public BigInteger rol (BigInteger a, int n)
public BigInteger ror (BigInteger a, int n)
public BigInteger sar (BigInteger a, int n)
shift with modulo-count (positive)
public BigInteger setbit (BigInteger a, int n)
public BigInteger shl (BigInteger a, int n)
shift with modulo-count (positive)
public BigInteger shr (BigInteger a, int n)
shift with modulo-count (positive)
public BigInteger sub (BigInteger a, BigInteger b)
public boolean testbit (BigInteger a, int n)
public BigInteger toUnsigned (BigInteger a)
Get the unsigned equivalent of the provided truncated integer.
Warning, this method is unsafe! The result may no longer be representable on bitsize bits.
public String toUnsignedHexString (BigInteger v)
public BigInteger truncate (BigInteger v)
Truncate and store as a signed value. The resulting integer 2-complement representation holds
on at most bitsize bits.
public BigInteger truncate (String val)
Truncate and store as a signed value. The resulting integer 2-complement representation holds
on at most bitsize bits.
Parameters
| val | string value (decimal, hex, or octal - with the right associated prefix or suffix) |
