Since the team on offense is allowed three outs, each out is considered one third of a defensive inning and is denoted as. Thus, the actual voltage level is sometimes unpredictable.Ī rare "ternary point" in common use is for defensive statistics in American baseball (usually just for pitchers), to denote fractional parts of an inning.
Where the signal is usually grounded to a certain reference, or at a certain voltage level, the state is said to be high impedance because it is open and serves its own reference. In this configuration the output of the circuit is actually not connected to any voltage reference at all.
The output is said to either be low ( grounded), high, or open ( high- Z). This is most commonly seen in CMOS circuits, and also in transistor–transistor logic with totem-pole output. In certain analog logic, the state of the circuit is often expressed ternary. Use of ternary numbers to balance an unknown integer weight from 1 to 40 kg with weights of 1, 3, 9 and 27 kg (4 ternary digits actually gives 3 4 = 81 possible combinations: −40 to +40, but only the positive values are useful) Nonary (base 9, each digit is two ternary digits) or septemvigesimal (base 27, each digit is three ternary digits) can be used for compact representation of ternary, similar to how octal and hexadecimal systems are used in place of binary. Compact ternary representation: base 9 and 27 The value of a binary number with n bits that are all 1 is 2 n − 1. Sum of the digits in ternary as opposed to binary decimal) nor is one-sixth (senary 1 / 10, decimal 1 / 6). Numbers from 1 to 3 3 in standard ternary TernaryĪs for rational numbers, ternary offers a convenient way to represent 1 / 3 as same as senary (as opposed to its cumbersome representation as an infinite string of recurring digits in decimal) but a major drawback is that, in turn, ternary does not offer a finite representation for 1 / 2 (nor for 1 / 4, 1 / 8, etc.), because 2 is not a prime factor of the base as with base two, one-tenth (decimal 1 / 10, senary 1 / 14) is not representable exactly (that would need e.g. However, they are still far less compact than the corresponding representations in bases such as decimal – see below for a compact way to codify ternary using nonary (base 9) and septemvigesimal (base 27). For example, decimal 365 or senary 1405 corresponds to binary 101101101 (nine digits) and to ternary 111112 (six digits). Representations of integer numbers in ternary do not get uncomfortably lengthy as quickly as in binary.
The Babylonians used cuneiform number characters, and although Unicode does acknowledge cuneiform characters, their use on computers remains rather impractical. Although the decimal numeral system has effectively eliminated all competition for human use, like duodecimal, sexagesimal shows many vestiges in our current usage, like the subdivisions of time (an hour into 60 minutes, and a minute into 60 seconds) or angle (an arc degree into 60 arc minutes, and a arc minute into 60 arc seconds). Sexagesimal was extensively used by the ancient Babylonians, albeit without a zero (they used extra spacing instead). The sexagesimal numeral system is a place-value notation using the powers of 60 (see A159991) rather than the powers of 10. This article page is a stub, please help by expanding it.
