LaTeX representation of hollow "R" symbol for real space?

Post by clayton »

In LaTeX, how do I represent the hollow "R" symbol that designates the real number space?

Thanks!

Hi,

use \mathbb from amsfonts (loaded by amssymb):

Code: Select all

\documentclass{report}
\usepackage{amssymb}

\begin{document}

$\mathbb{R}$

\end{document}
1,1,2,3,5,8,13,21,34,55,89,144,233,...

Just a note:
One normally represents the sets of natural numbers, integers, rational numbers, real numbers, and complex numbers by bold letters (at least on our math institut). I only use the `hollow' letters when writing on a blackboard.)

For the real numbers that is

Code: Select all

\mathbf{R}
instead of

Code: Select all

\mathbb{R}

I don't think that your math institute sets the standard [1,2]. Just by the way. The use of blackboard letters for this representation is very common.
