Well how do we represent 0.01 U.S. Dollars in Mark Twain Ecash(tm)? Easy-- we take a few bits of data, interpret it as an unsigned binary number, and then say "this number is how many U.S. pennies this coin is worth."
Now we're back to pennies again. I was more interested in your earlier claim of tiny payments, on the order of $2^-32.
Actually it can sometimes get more complicated than that, and there are some details about how the forthcoming ecashlib handles this to be found at "http://www.digicash.com/api".
Will the api make it possible to create coins of arbitrary value? Is the mint software (and the bank accountants) capable of doing floating point arithmetic? Matts

Matts, you don't want to do floating point for money, because floating point doesn't give you good control of precision. If you want to know how it _is_ done, RTFAPI ("read the fantastic API.") Scan for "EC_Coinage". Keep in mind that only Ecash(tm) Mints can create Ecash(tm) coins and choose what values the coins have. I'm glad you are asking these questions. Perhaps this will be the start of the Ecash(tm) API FAQ. Regards, Bryce (I'm getting tired of typing "(tm)". I'm going to make a macro that appends "(tm)" to every instance of "Ecash" as I type it...) - -----BEGIN GOODTIMES VIRUS INNOCULATION----- Copy me into your .sig for added protection! - ----- END GOODTIMES VIRUS INNOCULATION----- -----BEGIN PGP SIGNATURE----- Version: 2.6.2i Comment: Auto-signed under Unix with 'BAP' Easy-PGP v1.1b2 iQB1AwUBMaHk8UjbHy8sKZitAQFWcwMAsIK/HDloWq9LslPcQd3R0h6tOx1sH6I0 Ngc8jkSBsDPVL28I0tvimHLfMInq9EEPoOvwUjFQ8cmKTeVJVSRyYDCyQVTSbfWa 2gA8mjBTcCw5QrEYQAP74Dg0Os+iSwB5 =K79Z -----END PGP SIGNATURE-----
