# Uniform random number

> Supported in: Batch, Faster, Streaming

Returns a column of uniform random numbers drawn between 0 and 1. This is not deterministic and will not produce the same result on repeated builds, even when using a seed.

**Expression categories:** Numeric

## Declared arguments

* *optional* **Seed:** Adding a seed means that the random numbers will be generated from same sequence at each build. If you want true random numbers this should not be supplied. A seed will not produce fully deterministic results since compute may run distributed and the order in which random numbers are pulled for rows is not guaranteed.<br>*Literal\<Long>*

**Output type:** *Double*
