str
Any value as text, exactly as it prints: str(1/3) is "1/3". A number written as a decimal, str(1.2), or rounded to places, str(round(x, 2)), reads as a decimal ("1.2", "0.25") when its decimal ends.
value(any) -- the value
Strings
num
Reads text as a number, exactly: num("3/4") is 3/4, num("2.5e3") is 2500. A decimal() value is the number its digits name (num(decimal(5, 2))*2 is 10), a number itself.
s(text) -- digits, a fraction or a decimal; or a decimal() value

Whether the text begins with the given piece.
s(text) -- the textpart(text) -- the beginning to test

param
The text the page passed for the name with this run (set_param "name=value" before the run, the channel a slider's value comes by), else the default, else "". Not a control: nothing is shown and nothing is asked; the page decides what it passes. Works in the public wasm as in the cloud (not gated). The usual use is the kept chart layout, applyLayout(g, param("layout", "")), which the browser plotter's exportSvg passes under that name; a symbol, an interval or a title can come the same way.
name(text) -- the name the page passes the text underdefault(text) -- (optional) the text when the page passed none
