Blackboard signs for set of rationals (Q) and reals (R)?

Blackboard signs for set of rationals (Q) and reals (R)?

[Gerben Wierda]

Just a simple question I could not find the answer for in the docs.

What do I need to get the blackboard style (double lines) characters for R (the set of real numbers) and Q (the set of rational numbers) in a ConTeXt document?

I've been using \mathbb{R} and \mathbb{Q}, but apparently that's MkIV only.
However, {\blackboard R} and {\blackboard Q} seem to work both under MkII
and MkIV (although the glyph shapes are different, but I assume that's
font-related).

Cheers,

Thanks. That works. Any chance on getting these in italics/slanted?

Hi Gerben,

You can use ${\Bbb R}$ to get the set of real numbers (for instance…), both in mkii and mkiv.

Best regards: OK
