Fontsize

[Ulrich Dirr]

Hi,

is it possible now (with luatex or mkiv) to typeset a document in bp? I've
tried \setupbodyfont[9bp] but the resulting pdf uses 8,97bp which means 9pt
(TeX points)?

Ulrich

\chardef\fontdigits=2

\setupbodyfont[9bp]

\starttext
Text in nearly 9 bigpoints.
\stoptext

Yes and no, you're restricted to 2 digits after the decimal point, exact results
are only possible with a short modification.
