Expand description

TODO (howardwu): Update to use ToBitsLE and ToBitsBE. This defines a BigInteger, a smart wrapper around a sequence of u64 limbs, least-significant digit first.

Required methods

Add another representation to this one, returning the carry bit.

Subtract another representation from this one, returning the borrow bit.

Performs a leftwise bitshift of this number, effectively multiplying it by 2. Overflow is ignored.

Performs a leftwise bitshift of this number by some amount.

Performs a rightwise bitshift of this number, effectively dividing it by 2.

Performs a rightwise bitshift of this number by some amount.

Returns true iff this number is odd.

Returns true iff this number is even.

Returns true iff this number is zero.

Compute the number of bits needed to encode this number. Always a multiple of 64.

Compute the i-th bit of self.

Returns the big integer representation of a given big endian boolean array.

Returns the bit representation of the big integer in a big endian boolean array, without leading zeros.

Returns a vector for wnaf.

Provided methods

Returns the bit representation of the big integer in a little endian boolean array, with trailing zeroes.

Writes this BigInteger as a big endian integer. Always writes (num_bits / 8) bytes.

Reads a big endian integer occupying (num_bits / 8) bytes into this representation.
