The single number to repeat — for example a fixed price level, a setting, or the result of math.last.
Outputs
Buffer (time series)
A number line that holds the same value on every bar — a flat horizontal line.
Broadcast takes a single number and stretches it into a full line, repeating that one value on every bar. It’s the adapter you use when a tool wants a series but all you have is one fixed number.
How it works
Many tools (like Cross) compare two number lines bar-by-bar, but a single value such as a price level or a constant is just one number. Broadcast copies that value across the whole chart so it becomes a flat horizontal line the rest of the pipeline can read like any other series. It has no settings — it simply repeats input a.

Examples
Wire a fixed level like 1.2500 through Broadcast, then feed that flat line into Cross so price crossing the level fires a signal.
Broadcast a constant.number into the b input of math.arithmetic to add or scale a series by a fixed amount.
Common mistakes
Forgetting that Broadcast only repeats one value — it can’t turn a list of different numbers into a series; it makes a flat line, nothing more.
Broadcasting a value that should have stayed a single number, then wondering why a scalar-only input refuses the now-series connection.
