Convert string amount to currency format in the specified format

Objective

When doing financial projects, a large number of contacts of digital strings often need to be formatted to display, here I wrote a demo, the string amount is formatted, you can retain the number of decimal digits, you can add a currency identifier prefix.

Written in the prototype string, you need to format the right time to format the chant!

Example: ' 123345.23123 '. Moneyformatter (2, ' ￥ ')

Output: ' ￥123,345.23 '

The demo has a comment, so I don't have to do any more explaining.
