The condition is Integer input narrows the type of input to <Integer|String> & Integer, which distributes to Integer&Integer | String&Integer, which, as String and Integer are disjoint types, is equivalent to Integer&Integer | Nothing (Nothing is the empty bottom type), which simplifies to just Integer.

For example, when computing x 2 k −1, the binary method requires k−1 multiplications and k−1 squarings. However, one could perform k squarings to get x 2 k and then multiply by x −1 to obtain x 2 k −1. To this end we define the signed-digit representation of an integer n in radix b as
This section has a simplified version of the algorithm, showing how to compute the product of two natural numbers ,, modulo a number of the form +, where = is some fixed number. The integers a , b {\displaystyle a,b} are to be divided into D = 2 k {\displaystyle D=2^{k}} blocks of M {\displaystyle M} bits, so in practical implementations, it is ...
The Lenstra elliptic-curve factorization method to find a factor of a given natural number works as follows: . Pick a random elliptic curve over / (the integers modulo ), with equation of the form = + + together with a non-trivial point (,) on it.
Saturation arithmetic is a version of arithmetic in which all operations, such as addition and multiplication, are limited to a fixed range between a minimum and maximum value. If the result of an operation is greater than the maximum, it is set ("clamped") to the maximum; if it is below the minimum, it is clamped to the minimum. The name comes ...

numeric_std is a library package defined for VHDL.It provides arithmetic functions for vectors. Overrides of std_logic_vector are defined for signed and unsigned arithmetic.
