# parseint

> Parse a string as an integer in the given base.

`parseint(str, base)` converts the string representation of an integer to a number. `base` specifies the numeric base: `10` for decimal, `16` for hexadecimal, `2` for binary, and so on. The base must be between 2 and 62 inclusive.

## Signature

```
parseint(number string, base number) number
```

## Example

Read a replica count from an environment variable and use it in a deployment command:

```hcl theme={null}
computed "replicas" {
  description = "Number of replicas from CI environment"
  expression  = parseint(env("REPLICA_COUNT", "2"), 10)
}

task "scale" {
  description = "Scale the deployment to the configured replica count"
  commands    = ["kubectl scale deployment/api --replicas=${computed.replicas}"]
}
```

`env` returns a string. `parseint` converts it to a number so it can be used in numeric contexts or validated with [`min`](/functions/number/min) and [`max`](/functions/number/max).

## Notes

* `base` must be a whole number between 2 and 62 inclusive.
* If the string is not a valid integer in the given base, Errand reports an error at evaluation time.
* The result is always an integer. Decimals are not parsed by `parseint`.
