This is about (numerical) displays, eg. a "multiple-digit" display such as a https://en.wikipedia.org/wiki/Seven-segment_display (LED or LCD) and the difference between a digit as a single-glyph numeral (0-9) and a digit as referring to the possible position for a glyph on the display.
Example: "1.23" would be a three-digit display with the digits/glyphs/symbols "1","2","3" with the numeral "1.23" (representing a number). However, any digit (location) on that display could show different digits (glyph/symbol/value), e.g. the leftmost could show a "9" instead.
So the term "digit" is used ambiguously which makes it a little awkward, and I am looking for a way to distinguish between the two meanings - is there?
The awkwardness I was referring to may be clearer with yet another example: "Show a digit on the leftmost digit".
I guess it's a matter of context and better set up in a way that "Show a digit on the leftmost position" or similar would work - which is difficult when the context is the positional attribute.
Maybe introducing inaccuracy like "Show a number on the leftmost digit" is tolerable? But it is and sounds wrong.
Wikipedia states nothing about its use as "positional attribute":
A numerical digit is a single symbol (such as "2" or "5") used alone, or in combinations (such as "25"), to represent numbers (such as the number 25) according to some positional numeral systems. The single digits (as one-digit-numerals) and their combinations (such as "25") are the numerals of the numeral system they belong to.
So maybe there is a synonym for "digit" better suited to describe a position - perhaps "place" (from https://en.wiktionary.org/wiki/decimal_place, but not quite right either)?
