How to get Real Number symbol in LaTeX?

[George Ballinger]

Can someone please tell me how I can create the "classic" real number
symbol in LaTeX? I don't like the symbol generated by \Re. Also
\mathbb{R} and \mathbf{R} aren't what I'm looking for. I want
more of a combination of these two with a bold face R whose left
side consists of a double line.

I know the following packages:
- amsfonts (\mathbb)
- bbm (\mathbbm)
- bbold (?)
- doublestroke (?)

all available from a CTAN mirror near you.

Since it seems you don't know this, let me first say that \Re was never
meant to represent any set, but to be use as an operator as in the
following text book quote: If $z = x + iy$, the we call $x$ the
\emph{real part} of $z$ and write $x = \Re z$...". In my field (Complex
Analysis) you hardly ever see this anymore, upright "Re" is used
instead.

To get what you want, try \usepackage{amssymb} and then $\mathbb{R}$.
This uses the font msbm from the amsfonts package. There are other
choices of fonts that some prefer, including bbold. Look around CTAN for
such fonts and support files for LaTeX.

You should perhaps have a look at the Y&Y TeX page where the old AMS set
font can be found. It's perhaps what you are looking for...
