Value0

Value0 is not a standard mathematical or computer-science term with a fixed definition. It is most often encountered as an identifier or placeholder used in examples, documentation, and code to refer to the initial value of a sequence, the zeroth element, or a starting parameter.

In programming languages that use zero-based indexing, the first element of an array or list is at index 0, and in educational material it is sometimes described as value0. As a variable name, value0 is commonly used to initialize accumulators, counters, or state variables before a loop or computation.

In data formats and configuration files, keys named value0 may hold the first value in an ordered collection, such as the first feature value in a vector, or the initial measurement in a time series. Such usage is not standardized and depends on the specific project's naming conventions.

In mathematics, the term zeroth or index zero can refer to the starting term of a sequence or the value of a function at zero, f(0). While closely related, this use is separate from any particular label "value0" and is more about indexing and boundary values than a fixed symbol.
