Accuracy, rounding and tiny prices

Rounding

A coin’s screen carries the same rules wherever the rotation shows it:

One coin’s screen with its price, 24h percent change, 24h volume and a 24h chart, all in the ticker’s usual $ format

A price of a thousand dollars or more is written without decimals; from one dollar to a thousand with two; below a dollar with four significant places after its leading zeros. Volume and market cap are compact: T, B and M for trillions, billions and millions, two decimals, as in $1.73T. Percentages carry their sign and one or two decimals. The $ is always there; the ticker shows US dollars only.

Tiny prices

A coin worth a fraction of a cent would need a row of zeros. The glass writes it as $0.0, a small subscript count of the zeros that follow, then the significant digits, in every layout. The page describes it as a $0.0…052-style price shows the number of zeros as a small subscript.

Stale or missing data

The ticker never invents a figure. When a price cannot be fetched it shows -.-- with a dim note saying why, such as No reply or Busy (429), and during a server outage it keeps the last good screen on the glass and says how old it is. See Prices stopped updating.
