Hi list,
I'm trying to scale a text to the textwidth and textheight by keeping
the aspect ratio, using different papersizes.
When the dimensions get too big I get an "Arithmetic overflow".
(I'm trying to do something similar to resizebox in LaTeX:
http://tex.stackexchange.com/questions/55394/perfectly-scale-line-paragraph-image-anything-up-to-textwidth)
Minimal example:
\setuppapersize[A4][A4] %% [A1][A1]
\showframe
\starttext
\scale[factor=max,width=\textwidth,height=\textheight]{\framed[frame=on]{!}}
\stoptext
Error message:
! Arithmetic overflow.

Not sure where exactly, but likely you have reached a size calculation
limit of TeX (seems like a box calculation since more text works fine).
Start with the bigger font size if you want to enlarge the box that much:
\setuppapersize[A4][A4] %% [A1][A1]
\showframe
\starttext
\definedfont[Serif at 20pt]
\scale[factor=max,width=\textwidth,height=\textheight]{\framed[frame=on]{!}}
\stoptext

you can experiment with
\unprotect
\def\grph_scale_convert_large_scale#1#2#3#4%
{\edef#2{\ifnum#3=\plusthousand-\the\dimexpr#1\else\luaexpr{-\number#3*\number\dimexpr#1/1000}sp\fi}%
\edef#4{\luaexpr{\number#3/10}}}
\protect
