Re: Formula for Currency Conversion

[Eduard Sluis <eduard@xxxxxxxxxxxxxxxxxxxxxxx>]

If correct you have the rates against your base currency (buy, sell and mid 
rate).
Than you are going to convert from the from currency to the to currency.
When the to currency is your base currency:
 Multiply amount with the buy rate of the from currency. 
When the from currency is your base currency:
 Divide amount through the sell rate of the to currency.
When neither currency is your base currency:
 Convert first to your base currency using the Midrate.
 Convert than to the to currency using the sell rate.
 
Off course take acount the different decimal positions of the currencies and 
the rate against how many of each currency!!
 
Have fun,
Eduard.

I'm sure there's other solutions out there, but here's an idea:

What do you think about building/updating a table daily with all the
conversions? Using the example table below, $5 in japanese dollars is
equal to $2.50 in US dollars.

Example:
|----------+----------+----------+----------+----------|
| | | | | |
| | US | EUR | GBP | JPY |
| | | | | |
|----------+----------+----------+----------+----------|
| | | | | |
| JPY $1 | 0.5 | 1 | 0.75 | 1 |
| | | | | |
|----------+----------+----------+----------+----------|
| | | | | |
| US $1 | 1 | 0.5 | 0.8 | 0.3 |
| | | | | |
|----------+----------+----------+----------+----------|
| | | | | |
| ETC.. | | | | |
| | | | | |
|----------+----------+----------+----------+----------|

US EUR GBP JPY
JPY $1 0.5 1 0.75 1
US $1 1 0.5 0.8 0.3
ETC..
