Re: [NTG-context] test for (negative) number

Thanks for all the answers so far. The 'doifelse' should do the trick. I was hoping for a system macro, but if there is none, I have to program it myself. :-) Peter Am 21.08.2012 08:56, schrieb Wolfgang Schuster:

Hi Peter,

I recommend using the following handy little idiom: \ctxlua{commands.doifelse(-45 > 0)}{big}{small} % small

It lets you do all sorts of things that are tricky in TeX: \ctxlua{ commands.doifelse( string.len( "-45" ) > 5 ) }{long}{short}

Cheers, Sietse

For functions in the commands namespace you can write e.g. \ctxcommand{doifelse(…)}{…}{…} instead of \ctxlua{commands.doifelse(…)}{…}{…}.
