Namespace: Microsoft.Quantum.Arithmetic
Package: Microsoft.Quantum.Numerics
Computes the reciprocal 1/x for an unsigned integer x
using integer division. The result, interpreted as an integer,
will be floor(2^(2*n-1) / x)
.
operation ComputeReciprocalI (xs : Microsoft.Quantum.Arithmetic.LittleEndian, result : Microsoft.Quantum.Arithmetic.LittleEndian) : Unit is Adj + Ctl
Input
xs : LittleEndian
n-bit unsigned integer
result : LittleEndian
2n-bit output, must be in $\ket{0}$ initially.
Output : Unit
Remarks
For the input x=0, the output will be all-ones.
