# otp.Operation.float.eq

### eq(other, delta)

Compare two double values between themselves according to `delta` relative difference.
Calculated as `abs(column - other) <= delta`.

* **Parameters:**
  * **other** ([*Operation*](../root.md#onetick.py.Operation) *,* [*float*](https://docs.python.org/3/library/functions.html#float)) -- column or value to compare with
  * **delta** ([*Operation*](../root.md#onetick.py.Operation) *,* [*float*](https://docs.python.org/3/library/functions.html#float)) -- column or value with relative difference
* **Return type:**
  [Operation](../root.md#onetick.py.Operation)

### Examples

```pycon
>>> data = otp.Ticks(X=[1, 2.17, 10.31841, 3.141593, 6],
...                  OTHER=[1.01, 2.1, 10.32841, 3.14, 5],
...                  DELTA=[0, 1, 0.1, 0.01, 0.001])
>>> data["Y"] = (1 + data["X"] - 1).float.eq(data["OTHER"], data["DELTA"])
>>> otp.run(data)
                     Time          X     OTHER  DELTA    Y
