# max

> Return the largest of a set of numbers.

`max(numbers...)` returns the highest value from the given numbers.

## Signature

```
max(numbers... number) number
```

At least one argument is required.

## Example

Cap the concurrency to the number of available CPU cores, but never exceed a configured maximum:

```hcl theme={null}
variable "max_workers" {
  description = "Maximum number of parallel test workers"
  type        = number
  default     = 8
}

variable "min_workers" {
  description = "Minimum number of parallel test workers"
  type        = number
  default     = 2
}

computed "workers" {
  description = "Effective worker count"
  expression  = max(var.min_workers, var.max_workers)
}

task "test" {
  description = "Run the test suite with the computed worker count"
  commands    = ["go test -parallel ${computed.workers} ./..."]
}
```

## Notes

* All arguments must be numbers.
* To find the smallest value, use [`min`](/functions/number/min).
