• In some
programming languages (e.g.,
A+,
APL,
C++,
Go), iota (either as the lowercase symbol ⍳ or the identifier iota) is used to represent and generate an array of consecutive integers. For example, in APL ⍳4 gives 1 2 3 4. • The lowercase iota symbol is sometimes used to write the
imaginary unit, but more often Roman
i or
j is used. • In
mathematics, the
inclusion map of one space into another is sometimes denoted by the lowercase iota. • In
logic, the lowercase iota denotes the
definite descriptor. • Turned iota was formerly used for the
Sinological phonetic notation letter now transcribed as . ==Unicode==
