Please note, that all numbers of TBC and its divisions/multipliers are written in Tonal, not decimal. This means that instead of counting 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10-- you count: 0, 1, 2, 3, 4, 5, 6, 7, 8, , 9, , , , , , 10. Some higher-value digits may require installing a font.

* Tonal BitCoin and Decimal BitCoin can be differentiated by the pronunciation of the numbers. "One bitcoin", "two bitcoin", etc is decimal, but "an bitcoin", "de bitcoin" is tonal.

The total number of Tonal BitCoins ever (analogous to the 21mil BTC) is just under 7.76 tam-bitcoin.

For more information on the Tonal system in general, please see the book.

Guessing TBC or BTC

Given variable 'value' in base units (uBTCents/TBCᵇ), one can guess whether it is properly Decimal BitCoin or Tonal BitCoin with the following pseudo-code:

if ( ! ( this % 0x10000 ) )
	Choose Tonal BitCoin
if ( ! ( this % 1000000 ) )
	Choose Decimal BitCoin
if ( ! ( this % 0x100 ) )
	Choose Tonal BitCoin
