a decimal point, a fractional part (decimal digits), and an exponent part
(<code>e</code> or <code>E</code> followed by an optional sign and decimal digits).
One of the integer part or the fractional part may be elided; one of the decimal point
or the exponent part may be elided.
An exponent value exp scales the mantissa (integer and fractional part) by 10<sup>exp</sup>.

### SIG Big Data

During the 1.13 release cycle, SIG Big Data has been focused on community engagements relating to 3rd-party project integrations with Kubernetes. There have been no impacts on the 1.13 release.

### SIG CLI

* `apply` falls back to generic 3-way JSON merge patch for Third Party Resource or unregistered types ([#40666](https://github.com/kubernetes/kubernetes/pull/40666), [@ymqytw](https://github.com/ymqytw))

#### Updates to edit
* `edit` now supports Third party resources and extension API servers. ([#41304](https://github.com/kubernetes/kubernetes/pull/41304), [@liggitt](https://github.com/liggitt))

For the 1.9 release, SIG Storage made Kubernetes more pluggable and modular by introducing an alpha implementation of the Container Storage Interface (CSI). CSI will make installing new volume plugins as easy as deploying a pod, and enable third-party storage providers to develop their plugins without the need to add code to the core Kubernetes codebase.

* Third Party Resource tests in the e2e suite were incorrectly marked as part of the conformance bucket.  They are alpha and are not required for conformance. ([#52823](https://github.com/kubernetes/kubernetes/pull/52823), [@smarterclayton](https://github.com/smarterclayton))

[SIG API Machinery][] is responsible for all aspects of the API server: API registration and discovery, generic API CRUD semantics, admission control, encoding/decoding, conversion, defaulting, persistence layer (etcd), OpenAPI, third-party resources, garbage collection, and client libraries.

- Kubectl [get and describe](https://github.com/kubernetes/enhancements/issues/515) now works with extensions
- Nodes now support [third party monitoring plugins](https://github.com/kubernetes/enhancements/issues/606).
- A new [Scheduling Framework](https://github.com/kubernetes/enhancements/issues/624) for schedule plugins is now Alpha.

information. ([#58418](https://github.com/kubernetes/kubernetes/pull/58418), [@yujuhong](https://github.com/yujuhong))

* The Kubelet now explicitly registers all of its command-line flags with an internal flagset, which prevents flags from third party libraries from unintentionally leaking into the Kubelet's command-line API. Many unintentionally leaked flags are now marked deprecated, so that users have a chance to migrate away from them before they are removed. In addition, one previously leaked...

  It is possible that this will cause problems with some third-party components
  that improperly depended on those rules. If this affects you, you can run
  `kubelet` with `--feature-gates=IPTablesOwnershipCleanup=false`, but a bug should also be filed against the third-party component. ([#114472](https://github.com/kubernetes/kubernetes/pull/114472), [@danwinship](https://github.com/danwinship))

* Fixed a bug in the single-numa-node policy of the TopologyManager.  Previously, pods that only requested CPU resources and did not request any third-party devices would fail to launch with a TopologyAffinity error. Now they will launch successfully. ([#83697](https://github.com/kubernetes/kubernetes/pull/83697), [@klueska](https://github.com/klueska))
