Provides a command to print a number with (potentially different) separators every three digits in the parts either side of the decimal point (the point itself is also configurable). The macro is fully expandable and not fragile (unless one of the separators is). There is also a command \sepnumform, that may be used when defining \the<counter> macros.

See also comma numprint.
