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

[Michael Langguth]

Dear Beáta,

I suppose, the sprintf-function can help you here. It's a 
function to convert floats (and doubles) to formatted 
strings.
For example, an appropriate format for your bias-values 
may be

sprintf("%10.5g",bias)

where the exponential notation is used as long as the 
precision being defined by the number 5.

For further examples, you can also consult the attached 
link:

Best regards
Michael
