Static Methods

add64(BigInt x, BigInt y, int carry) → (BigInt, int)

Add64 returns the sum with carry of x, y and carry: sum = x + y + carry. The carry input must be 0 or 1; otherwise the behavior is undefined. The carryOut output is guaranteed to be 0 or 1.

mul64(BigInt x, BigInt y) → (BigInt, BigInt)

Mul64 returns the 128-bit product of x and y: (hi, lo) = x * y with the product bits' upper half returned in hi and the lower half returned in lo.

sub64(BigInt x, BigInt y, int borrow) → (BigInt, int)

Sub64 returns the difference of x, y and borrow: diff = x - y - borrow. The borrow input must be 0 or 1; otherwise the behavior is undefined. The borrowOut output is guaranteed to be 0 or 1.
