Namespace: Microsoft.Quantum.Arithmetic

Package: Microsoft.Quantum.Numerics

Adds two fixed-point numbers stored in quantum registers.

operation AddFxP (fp1 : Microsoft.Quantum.Arithmetic.FixedPoint, fp2 : Microsoft.Quantum.Arithmetic.FixedPoint) : Unit is Adj + Ctl

Description

Given two fixed-point registers respectively in states $\ket{f_1}$ and $\ket{f_2}$, performs the operation $\ket{f_1} \ket{f_2} \mapsto \ket{f_1} \ket{f_1 + f_2}$.

Input

fp1 : FixedPoint

First fixed-point number

fp2 : FixedPoint

Second fixed-point number, will be updated to contain the sum of the two inputs.

Output : Unit

Remarks

The current implementation requires the two fixed-point numbers to have the same point position counting from the least-significant bit, i.e., $n_i$ and $p_i$ must be equal.
