The type of real numbers is a locally (-1)-connected? Hausdorff sober? Archimedean ordered field with a compact? real unit interval? .
There are many other different types which are called real numbers in the literature, many of which are do not satisfy the same properties as listed above for the real numbers. These include:
localic real numbers?
MacNeille real numbers? or Dedekind-MacNeille real numbers
real unit interval? based real numbers
pre-algebra real numbers, real numbers as usually defined in school mathematics.
Euclidean real numbers? or Escardo-Simpson real numbers
The various types of real numbers defined by Peter Freyd using various definitions of the co-algebraic real unit interval.
Stolzenberg real numbers? from closed intervals of rational numbers, originally defined by Gabriel Stolzenberg.
