qrisp.q_round

q_round(a: QuantumFloat) → QuantumFloat

Computes out-of-place the rounding of a QuantumFloat to the first significant digit.

Parameters:

aQuantumFloat

Returns:

QuantumFloat

The rounding of a.

Examples

>>> from qrisp import *
>>> a = QuantumFloat(4,-2)
>>> a[:] = {0.25: 0.25**0.5, 1.75: 0.75**0.5}
>>> b = q_round(a)
>>> b.get_measurement()
{2.0: 0.75, 0.0: 0.25}

Warning

Rounding operations that would result in overflow, raise no errors. Instead, the operations are performed modular.
