##### `m.room.power_levels` events accept values as floats
|
||||
|
||||
When the value is a float, anything after the decimal point is removed,
|
||||
making e.g. `5.17`, `5.42`, and `5` functionally identical.
|
||||
When the value is a float
|
||||
* First, exponential notation is applied: `5.114698E4` becomes `51146.98`
|
||||
* Second, the value is truncated at the decimal point: `51146.98` becomes `51146`.
|
||||
|
||||
Any float greater than or equal to `1e309` must result in the powerlevel event
|
||||
being rejected.

For example, this is a valid `m.room.power_levels` event in this room version:

In this example, both `@bob:localhost` and `@alice:localhost` have the same effective
|

power level of `50`, even though the values are technically different.

|

When a float written in exponential notation is unpacked, the decimal portion is removed
|
||||
afterward; for example, `5.114698E4` becomes `51146.98`, which is then truncated to `51146`.

Note that, since this room version does not enforce that events comply with the requirements
|
||||
of [Canonical JSON](/appendices#canonical-json), power levels can be formatted as floats.
