the x sizes are just for text while the a-d sized are for titles and so

nowadays the a-d sizes could be defined in terms of larger bodyfont 
sizes as font class switching is pretty fast

for smaller sizes you can switch to a smaller bodyfont

\definealternativestyle [bigger]  [\setbigbodyfont  \tf] []
\definealternativestyle [smaller] [\setsmallbodyfont\tf] []

\starttext

{
     1\smaller this looks bad \mathematics{x}, too. \the\bodyfontsize\par
     2\smaller this looks bad \mathematics{x}, too. \the\bodyfontsize\par
     3\smaller this looks bad \mathematics{x}, too. \the\bodyfontsize\par
     4\smaller this looks bad \mathematics{x}, too. \the\bodyfontsize\par
}

{
     1\bigger this looks bad \mathematics{x}, too. \the\bodyfontsize\par
     2\bigger this looks bad \mathematics{x}, too. \the\bodyfontsize\par
     3\bigger this looks bad \mathematics{x}, too. \the\bodyfontsize\par
     4\bigger this looks bad \mathematics{x}, too. \the\bodyfontsize\par
}

i'll add the bigger and smaller shortcuts

Re: font size in math mode

[Armin Varmaz]

Hi Hans, hi guys,


thanks for the explanation! 


Does this mean that each time I want to change the font size of the text (e.g. for a floating object or framed text) I must do this manually for mathematics? or is there a way to adopt the font size of the text to mathematics? see below for an example what I mean. Here, I used definetextbackground but the effect remains in floating objects as well. I tried different font styles and different font types, too.


Armin  

********** EXAMPLE


\definealternativestyle[ImportantStyle][{\definedfont[Kurier-Bold at 24pt]}]


\definetextbackground[zhu]
 [location=paragraph,
 background=color,backgroundcolor=orange,
 leftoffset=0.5\bodyfontsize,rightoffset=.5\bodyfontsize,
 topoffset=.5\bodyfontsize,bottomoffset=.5\bodyfontsize,
 style=ImportantStyle,
 frame=off]


\startsetups important:start
 \starttextbackground[zhu]
\stopsetups


\startsetups important:stop
 \endgraf
 \stoptextbackground
\stopsetups


\definestartstop
 [important]
 [before=\setups{important:start},
 after=\setups{important:stop}]


\starttext


this looks normal $x$.


\startimportant
this uses the environment definetextbackground \mathematics{x}.
\stopimportant
\stoptext

****** END EXAMPLE

indeed, as math is using another font (or more fonts), so best then do:

\switchtobodyfont[small]\bf

or so. An other alternative is to define a few more sizes:

\setupbodyfontenvironment[default][p=0.8,q=0.6]

\definefontsize[p] \definefontsize[q]

\usetypescript[palatino]

test $x$ {\tfp test $x$} {\tfq test $x$} test
