qrisp.q_div#

q_div(numerator, divisor, prec=None)[source]#

Performs division up to arbitrary precision and uncomputes the remainder.

Parameters:

numeratorQuantumFloat: The QuantumFloat to divide.
divisorQuantumFloat: The QuantumFloat to divide by.
precint, optional: The precision of the division. If the precision is set to $k$ , the approximated quotient $q_{a p r}$ and the true quotient $q_{t r u e}$ satisfy $| q_{a p r} - q_{t r u e} | < 2^{- k}$ . By default, a suited precision will be determined from the other inputs.

Returns:

quotientQuantumFloat: The result of the division.

Examples

We calculate 10/8:

>>> from qrisp import QuantumFloat, q_div
>>> num = QuantumFloat(4)
>>> div = QuantumFloat(4)
>>> num[:] = 10
>>> div[:] = 8
>>> quotient = q_div(num, div, prec = 2)
>>> print(quotient)
{1.25: 1.0}
