# What's the technical term for “place-value”?

When talking about positional notation, is there a technical term for "place-value" (as in, "the place-value of the 9 in 792 is 10), or is that it? Somehow, "place-value" sounds informal, but I don't know that I've heard an alternative ("magnitude" seems close, but it's more general).

• One term is positional notation. You may also encounter radix notation. – Brian M. Scott Feb 28 '16 at 21:47
• Just to be clear, there's the power of the $N$ by which you multiply each digit in a base-$N$ number, and there's the entire idea of "base-$N$". Either one of them might be called "place value"; are you specifically asking about the first kind of "place value" (the power of $N$ at a particular place in the numerical representation)? – David K Feb 28 '16 at 23:41
• @DavidK Yes, I'm asking about the first, as in, "the place-value of the 9 in 792 is 10" – ivan Feb 28 '16 at 23:55
