Number::Format is a library for formatting numbers.  Functions are
provided for converting numbers to strings in a variety of ways, and to
convert strings that contain numbers back into numeric form.  The output
formats may include thousands separators - characters inserted between
each group of three characters counting right to left from the decimal
point.  The characters used for the decimal point and the thousands
separator come from the locale information or can be specified by the
user.
