Constructors |
Assignment operators |
|
Numeric ordering, treating the value as an unsigned integer rather than a byte blob. |
|
Tests whether the value equals a 64‐bit unsigned number. |
|
Hex encoding of the number (with the most significant digits first). |
|
Returns the low 64 bits of the value. |
|
Returns the value as a human‐readable string. |
|
Returns the position of the highest bit set plus one, or zero if the value is zero. |
|
Converts the value to a double‐precision floating‐point number. |
|
Applies a bitwise AND with another big integer in place. |
|
Multiplication assignment operators |
|
Increment operators |
|
Addition assignment operators |
|
Returns the two's‐complement negation of the value. |
|
Decrement operators |
|
Subtraction assignment operators |
|
Divides this value by another big integer in place. |
|
Shifts the value left by the given number of bits in place. |
|
Shifts the value right by the given number of bits in place. |
|
Bitwise exclusive‐or assignment operators |
|
Bitwise disjunction assignment operators |
|
Returns the bitwise complement of the value. |
|
Returns the size in bytes of the internal representation. |
