# forceQuality

> Returns the given value, but overwrites the quality of that value.

**This function is used by Ignition's Expression language.**

## Description
Returns the given value, but overwrites the quality of that value. See the [quality codes](https://www.docs.inductiveautomation.com/docs/7.9/tags/understanding-tags/tag-quality-and-overlays.md#primary-data-qualities) for a list of potential quality codes. If the quality argument is omitted, the quality will be GOOD (192). This is a way to have expressions opt-out of the quality overlay system. You can also force a specific quality code here by including the quality argument.

:::caution
Be aware the quality codes linked in the description above access the 7.9 quality codes, which are the codes the forceQuality function uses. For an option using the 8.1 quality codes, see the [qualifiedValue](qualifiedValue.md) function page.
