### blackboard bold numbers

###### Wed 16 April 2014
In [latex]LaTeX[/latex], rendering blackboard bold is quite easy in math mode: use \mathbb{}:
[latex]mathbb{ABCDEFGHIJKLMNOPQRSTUVWXYZ}[/latex].
But this does not work with lower case:
[latex]mathbb{abcdefghijklmnopqrstuvwxyz}[/latex]
or with digits: [latex]mathbb{0123456789}[/latex]
a easy contermeasure is to use the command \mathbbm{} provided by the package bbm. This work for all lowercase letters and for some digits, including the 1.
