## Converting between distribution formats
|
||||
|
||||
Recall the [three formats of distributions](https://develop--squiggle-documentation.netlify.app/docs/Discussions/Three-Types-Of-Distributions). We can force any distribution into `SampleSet` format
|
||||
|
||||
<SquiggleEditor initialSquiggleString="toSampleSet(normal(5, 10))" />
|
||||
<SquiggleEditor

Or `PointSet` format
|

|

|
||||
|
||||
### `toSampleSet` has two signatures
|
||||
|
||||
Above, we saw the unary `toSampleSet`, which uses an internal hardcoded number of samples. If you'd like to provide the number of samples, it has a binary signature as well (floored)
|
||||
|
||||
<SquiggleEditor initialSquiggleString="[toSampleSet(0.1 to 1, 100.1), toSampleSet(0.1 to 1, 5000), toSampleSet(0.1 to 1, 20000)]" />
