This Swift Playground contains a few simple extension functions to the Swift Double type that I've found useful in my own projects.
Returns a string representation of a Double value. Accepts arguments for: maxDecimal
- Defaults to 2 decimal places
- Passing in a custom value minDecimal -> No default
- No default, optional value
- When passing in a value, if the minDecimal is greater than the maxDecimal value (default of 2), the maxDecimal will also be set to the value passed in for minDecimal withCommas -> Defaults to true
- Defaults to true
- Returns a string with commas at the traditional places (thousands, millions, etc.)
Simply copy and the paste the extension Double { } portion of the playground into your project. You can include the extension in its own file or within an existing Swift file in your project.

I typically make things for the situations that they're needed in but I like to share my work and I'm sure there are plenty of ways that this can be improved. Please let me know if you have any cool suggestions!
