There are supposed to be infinitely more real numbers than integers. But if you can name a real number, I can map it to an integer by converting the string you use to define the number to a bigint. This mapping suffers from mapping all definitions of pi to different integers, but that's OK. What is the mathematical term for "namable numbers"? That's what I'm talking about here, and it also seems related to the blog.
- mcphage 4y ago> What is the mathematical term for "namable numbers" Well, it depends on what you mean by "nameable"—a common one is "Algebraic number", which is means "a root of a polynomial with integer coefficients". That's a bigger list that "those you can define using addition, subtraction, multiplication, division, exponents". But if you use a different list of operations, you get a different set of numbers.
