printing Scientific notation of float

Hi,
Does Pharo have scientific float notation printing?
http://en.wikipedia.org/wiki/Scientific_notation

I want to control the length of string of a float in my GUI.

Thanks

If you mean

'"%e".' printf: 0.0000000061. --> '"6.1".'

There is some support here: http://www.squeaksource.com/Printf.html

bug report

In reply to this post by hernanmd

'Here is a float "%e" and an integer "%d".' printf: #(0.000000000001 42).
evalutes to
'Here is a float "1.0" and an integer "42".'

I think 'Here is a float "1.0e-12" and an integer "42".' is the right answer.
