Re: [boost] [multiprecision] Creation from a range

Is there any way to create an Integer (or a number) from a range (bounded or counted)?; or from a string_view (string_ref)?

Roughly speaking, something like:

XintXXX_t make_from_bounded_range(I f, I l); XintXXX_t make_from_counted_range(I f, size_t n);

What are the semantics?

I want to extract integers from a range (range of characters). Consider: char buff[] = "12345 67890"; auto a = make_from_bounded_range(buff, buff + 5); auto b = make_from_counted_range(buff, 5); auto c = make_from_bounded_range(buff + 6, buff + 6 + 5); auto d = make_from_counted_range(buff + 6, 5); cout << a << '\n' << b << '\n' << c << '\n' << d << '\n'; Prints: 12345 12345 67890 67890 How can I do this today with Boost multiprecision? I don't want to copy characters to a temporal buffer.

Is this a measure? Like an integer distance between borders?

I don't understand these questions. The numbers could be anything.
