There have been some proposals for standardisation. The common names are derived somewhat arbitrarily from a mix of Latin and Greek, in some cases including roots from both languages within a single name.

In this clock, each column of LEDs shows a binary-coded decimal numeral of the traditional sexagesimal time. Standard positional numeral systems Ī binary clock might use LEDs to express binary values. Numeral systems are classified here as to whether they use positional notation (also known as place-value notation), and further categorized by radix or base. 2.2 Non-standard positional numeral systems.2.1 Standard positional numeral systems.
