Ah! I think we should document this in the code clearly.

This has deviated too much from main, closing it for now. We can make a new refactor PR if needed

Sample code snippet: ```py import sympy from qualtran.bloqs.basic_gates import ZPowGate t, eps = sympy.symbols(r"t \epsilon") bloq = ZPowGate(exponent=t, eps=eps) print(bloq.t_complexity()) ``` Prints `TComplexity(rotations=1)`. One could do `bloq.t_complexity().t_incl_rotations(eps)`, but this `eps`...

`.t_complexity()` raises a `TypeError` for the second and third examples.

We should also override `ZPowGate.get_ctrl_system` to return a `CZPowGate` (similar to other basic gates).

@tanujkhattar's comment: > It's better to store frequency of `eps` by assuming we can represent float `eps` as a fraction `x / 2^{precision}` and store frequencies of `x`; with `precision`...

@mpharrigan ptal!

The code snippet I was trying to use (which works with this PR): ```py import sympy from qualtran.bloqs.basic_gates import ZPowGate from qualtran.resource_counting import get_cost_value, QECGatesCost t, eps = sympy.symbols(r"t \epsilon")...

Unfortunately not, we are still using `fxpmath.Fxp` to convert input floats to bits, which seems to be very slow.
