+- `separator: content = sym.space.narrow` : Separator between groups. 
 - `threshold: int | dictionary = 5` : Necessary number of digits needed for digit grouping to kick in. Four-digit numbers for example are usually not grouped at all since they can still be read easily. This parameter also accepts dictionary arguments of the form `(integer: int, fractional: int)` to allow turning on grouping for only the integer or fractional part, for example `(integer: 5, fractional: calc.inf)`.
