decimify

Parse numbers with different formatting to builtin python Decimal.

A decimal separator is a symbol used to separate the integer part from the fractional part of a number written in decimal form (e.g. "." in 12.45). Different countries officially designate different symbols for use as the separator. The choice of symbol also affects the choice of symbol for the thousands separator used in digit grouping.

Some examples of large number presentations in all around the world:
