[ncl-talk] how can I write large float value with e scientific notation?

[Adam Phillips]

Hi Beáta,

I would suggest copying the taylor_metrics_table.ncl function to the top of
your script, and rename it. Then, you can modify it as you like and call it
within your main script.
https://www.ncl.ucar.edu/Applications/Scripts/taylor_metrics_table.ncl

The line that is causing your issue is this line:
gsn_text_ndc(wks,sprintf("%4.3f",values(icase,iseas,im)),ixtbox,iytbox,
mv_tRes)

Following Michael's suggestion, you could put in an if statement like this:
if (values(icase,iseas,im).gt.100000) then
   gsn_text_ndc(wks,sprintf("%4.2g",values(icase,iseas,im)),ixtbox,iytbox,
mv_tRes)
else
   gsn_text_ndc(wks,sprintf("%4.3f",values(icase,iseas,im)),ixtbox,iytbox,
mv_tRes)
end if

Hope that helps!
Adam
